Luminescence device and display apparatus

[0001] This application is a division of Ser. No. 11/329,181, filed Jan. 11, 2006, now U.S. Pat. No. 7,544,426 which is a division of application Ser. No. 10/073,012, filed Feb. 12, 2002, now U.S. Pat. No. 7,147,935, which is a continuation of International Application PCT/JP01/10487, filed Nov. 30, 2001. All prior applications are incorporated herein by reference.

[0002] The present invention relates to an organic luminescence device (also called an organic electroluminescence device or organic EL device) for use in a planar light source, a planar display, etc. Particularly, the present invention relates to a novel metal coordination compound and a luminescence device having a high luminescence efficiency and causing little change with time by using a metal coordination compound of a specific structure.

[0003] An old example of organic luminescence device is, e.g., one using luminescence of a vacuum-deposited anthracene film (Thin Solid Films, 94 (1982) 171). In recent years, however, in view of advantages, such as easiness of providing a large-area device compared with an inorganic luminescence device, and possibility of realizing desired luminescence colors by development of various new materials and drivability at low voltages, an extensive study thereon for device formation as a luminescence device of a high-speed responsiveness and a high efficiency, has been conducted.

[0004] As precisely described in Macromol. Symp. 125, 1-48 (1997), for example, an organic EL device generally has an organization comprising a pair of upper and lower electrodes formed on a transparent substrate, and organic material layers including a luminescence layer disposed between the electrodes.

[0005] In the luminescence layer, aluminum quinolinol complexes (inclusive of Alq3 shown hereinafter as a representative example) having an electron-transporting characteristic and a luminescence characteristic, are used for example. In a hole-transporting layer, a material having an electron-donative property, such as a triphenyldiamine derivative (inclusive of α-NPD shown hereinafter as a representative example), is used for example.

[0006] Such a device shows a current-rectifying characteristic such that when an electric field is applied between the electrodes, holes are injected from the anode and electrons are injected from the cathode.

[0007] The injected holes and electrons are recombined in the luminescence layer to form excitons, which emit luminescence when they are transitioned to the ground state.

[0008] In this process, the excited states include a singlet state and a triplet state and a transition from the former to the ground state is called fluorescence and a transition from the latter is called phosphorescence. Materials in theses states are called singlet excitons and triplet excitons, respectively.

[0009] In most of the organic luminescence devices studied heretofore, fluorescence caused by the transition of a singlet exciton to the ground state, has been utilized. On the other hand, in recent years, devices utilizing phosphorescence via triplet excitons have been studied.

[0010] Representative published literature may include:

• • [0011] Article 1: Improved energy transfer in electrophosphorescent device (D. F. O'Brien, et al., Applied Physics Letters, Vol. 74, No. 3, p. 422 (1999)); and
  • [0012] Article 2: Very high-efficiency green organic light-emitting devices based on electrophosphorescence (M. A. Baldo, et al., Applied Physics Letters, Vol. 75, No. 1, p. 4 (1999)).

[0013] In these articles, a structure including four organic layers sandwiched between the electrodes, and the materials used therein include carrier-transporting materials and phosphorescent materials, of which the names and structures are shown below together with their abbreviations.

• • [0014] Alq3: aluminum quinolinol-complex
  • [0015] α-NPD: N4,N4′-di-naphthalene-1-yl-N4,N4′-diphenyl-biphenyl-4,4′-diamine
  • [0016] CBP: 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline
  • [0017] PtOEP: platinum-octaethylporphyrin complex
  • [0018] Ir(ppy)₃: iridium-phenylpyridine complex

[0019]

[0020] The above-mentioned Articles 1 and 2 both have reported structures, as exhibiting a high efficiency, including a hole-transporting layer comprising α-NPD, an electron-transporting layer comprising Alq3, an exciton diffusion-preventing layer comprising BCP, and a luminescence layer comprising CBP as a host and ca. 6% of PtOEP or Ir(ppy)₃ as a phosphorescent material dispersed in mixture therein.

[0021] Such a phosphorescent material is particularly noted at present because it is expected to provide a high luminescence efficiency in principle for the following reasons. More specifically, excitons formed by carrier recombination comprise singlet excitons and triplet excitons in a probability ratio of 1:3. Conventional organic EL devices have utilized fluorescence of which the luminescence efficiency is limited to at most 25%. On the other hand, if phosphorescence generated from triplet excitons is utilized, an efficiency of at least three times is expected, and even an efficiency of 100%, i.e., four times, can be expected in principle, if a transition owing to intersystem crossing from a singlet state having a higher energy to a triplet state is taken into account.

[0022] However, like a fluorescent-type device, such an organic luminescence device utilizing phosphorescence is generally required to be further improved regarding the deterioration of luminescence efficiency and device stability.

[0023] The reason of the deterioration has not been fully clarified, but the present inventors consider as follows based on the mechanism of phosphorescence.

[0024] In the case where the luminescence layer comprises a host material having a carrier-transporting function and a phosphorescent guest material, a process of phosphorescence via triplet excitons may include unit processes as follows:

• • [0025] 1. transportation of electrons and holes within a luminescence layer,
  • [0026] 2. formation of host excitons,
  • [0027] 3. excitation energy transfer between host molecules,
  • [0028] 4. excitation energy transfer from the host to the guest,
  • [0029] 5. formation of guest triplet excitons, and
  • [0030] 6. transition of the guest triplet excitons to the ground state and phosphorescence.

[0031] Desirable energy transfer in each unit process and luminescence are caused in competition with various energy deactivation processes.

[0032] Needless to say, a luminescence efficiency of an organic luminescence device is increased by increasing the luminescence quantum yield of a luminescence center material.

[0033] Particularly, in a phosphorescent material, this may be attributable to a life of the triplet excitons which is longer by three or more digits than the life of a singlet exciton. More specifically, because it is held in a high-energy excited state for a longer period, it is liable to react with surrounding materials and cause polymer formation among the excitons, thus incurring a higher probability of deactivation process resulting in a material change or life deterioration.

[0034] Further, in view of the formation of a full-color display device, luminescence materials providing luminescence colors which are as close as possible to pure three primary colors of blue, green and red, are desired, but there have been few luminescence materials giving a luminescence color of pure red, so that the realization of a good full-color display device has been restricted.

[0035] Accordingly, a principal object of the present invention is to provide a compound capable of high efficiency luminescence and showing a high stability as a luminescent material for use in a phosphorescent luminescence device. Particularly, it is an object to provide a luminescence material compound which is less liable to cause energy deactivation in a long life of excited energy state and is also chemically stable, thus providing a longer device life. A further object of the present invention is to provide a red luminescence material compound capable of emitting pure red suitable for forming a full-color display device.

[0036] Inclusively, principal objects of the present invention are to provide a luminescence material which exhibits a high luminescence efficiency, retains a high luminance for a long period and is capable of red luminescence based on phosphorescent luminescence materials, and also provide a luminescence device and a display apparatus using the same.

[0037] In the present invention, a metal complex is used as a luminescence material, particularly a novel luminescent metal complex compound comprising iridium as a center metal and an isoquinolyl group as a ligand.

[0038] More specifically, the present invention uses as a luminescence material a metal coordination compound having at least one partial structure represented by formula (1) below:

[0081] An organic luminescence device, wherein the organic compound comprises a metal coordination compound having a structure represented by the formula (3).

[0085] An organic luminescence device, wherein the phosphorescence is red in luminescence color.

[0086] A picture display apparatus, comprising the above-mentioned organic luminescence device, and a means for supplying electric signals to the organic luminescence device.

[0100] Basic structures of organic EL devices formed according to the present invention are illustrated in FIGS. 1(a), (b) and (c).

[0101] As shown in FIG. 1, an organic luminescence device generally comprises, on a transparent electrode 15, a 50 to 200 nm-thick transparent electrode 14, a plurality of organic film layers and a metal electrode 11 formed so as to sandwich the organic layers.

[0102] FIG. 1(a) shows an embodiment wherein the organic luminescence device comprises a luminescence layer 12 and a hole-transporting layer 13. The transparent electrode 14 may comprise ITO, etc., having a large work function so as to facilitate hole injection from the transparent electrode 14 to the hole-transporting layer 13. The metal electrode 11 comprises a metal material having a small work function, such as aluminum, magnesium or alloys of these elements, so as to facilitate electron injection into the organic luminescence device.

[0103] The luminescence layer 12 comprises a compound according to the present invention. The hole-transporting layer 13 may comprise, e.g., a triphenyldiamine derivative, as represented by α-NPD mentioned above, and also a material having an electron-donative property as desired.

[0104] A device organized above exhibits a current-rectifying characteristic, and when an electric field is applied between the metal electrode 11 as a cathode and the transparent electrode 14 as an anode, electrons are injected from the metal electrode 11 into the luminescence layer 12, and holes are injected from the transparent electrode 15. The injected holes and electrons are recombined in the luminescence layer 12 to form excitons, which cause luminescence. In this instance, the hole-transporting layer 13 functions as an electron-blocking layer to increase the recombination efficiency at the boundary between the luminescence layer 12 and the hole-transporting layer 13, thereby providing an enhanced luminescence efficiency.

[0105] Further, in the structure of FIG. 1(b), an electron-transporting layer 16 is disposed between the metal electrode 11 and the luminescence layer 12 in FIG. 1(a). As a result, the luminescence function is separated from the functions of electron transportation and hole transportation to provide a structure exhibiting more effective carrier blocking, thus increasing the luminescence efficiency. The electron-transporting layer 16, may comprise, e.g., an oxadiazole derivative.

[0106] FIG. 1(c) shows another desirable form of a four-layer structure, including a hole-transporting layer 13, a luminescence layer 12, an exciton diffusion prevention layer 17 and an electron-transporting layer 16, successively from the side of the transparent electrode 14 as the anode.

[0107] The luminescence materials used in the present invention are most suitably metal coordination compounds represented by the above-mentioned formulae (1) to (9), which are found to cause high-efficiency luminescence in a red region around 600 mm, retain high luminance for a long period and show little deterioration by current passage.

[0108] The metal coordination compound used in the present invention emits phosphorescence, and its lowest excited state is believed to be an MLCT* (metal-to-ligand charge transfer) excited state or π-π* excited state in a triplet state, and phosphorescence is caused at the time of transition from such a state to the ground state.

<<Measurement Methods>>

[0109] Hereinbelow, methods for measurement of some properties and physical values described herein for characterizing the luminescence material of the present invention will be described.

• • [0110] (1) Judgment between phosphorescence and fluorescence

[0111] The identification of phosphorescence was effected depending on whether deactivation with oxygen was caused or not. A solution of a sample compound in chloroform after aeration with oxygen or with nitrogen is subjected to photoillumination to cause photo-luminescence. The luminescence is judged to be phosphorescence if almost no luminescence attributable to the compound is observed with respect to the solution aerated with oxygen but photo-luminescence is confirmed with respect to the solution aerated with nitrogen. In contrast thereto, in the case of fluorescence, luminescence attributable to the compound does not disappear even with respect to the solution aerated with oxygen. The phosphorescence of all the compounds of the present invention has been confirmed by this method unless otherwise noted specifically.

• • [0112] (2) Phosphorescence yield (a relative quantum yield, i.e., a ratio of an objective sample's quantum yield Φ(sample) to a standard sample's quantum yield Φ(st)) is determined according to the following formula:
    Φ(sample)/Φ(st)=[Sem(sample)/Iabs(sample)]/[Sem(st)/Iabs(st)],
    wherein Iabs(st) denotes an absorption coefficient at an excitation wavelength of the standard sample; Sem(st), a luminescence spectral areal intensity when excited at the same wavelength: Iabs(sample), an absorption coefficient at an excitation wavelength of an objective compound; and Sem(sample), a luminescence spectral areal intensity when excited at the same wavelength.

[0113] Phosphorescence yield values described herein are relative values with respect a phosphorescence yield Φ=1 of Ir(ppy)₃ as a standard sample.

• • [0114] (3) A method of measurement of phosphorescence life is as follows.

[0115] A sample compound is dissolved in chloroform and spin-coated onto a quartz substrate in a thickness of ca. 0.1 μm and is exposed to pulsative nitrogen laser light at an excitation wavelength of 337 nm at room temperature by using a luminescence life meter (made by Hamamatsu Photonics K.K.). After completion of the excitation pulses, the decay characteristic of luminescence intensity is measured.

[0116] When an initial luminescence intensity is denoted by I₀, a luminescence intensity after t(sec) is expressed according to the following formula with reference to a luminescence life τ(sec):
I=I₀·exp(−t/τ).

[0117] Thus, the luminescence life r is a time period in which the luminescence intensity I is attenuated down to 1/e of the initial intensity I (I/I₀=e⁻¹, e is a base of natural logarithm). A luminescence life of 80 nsec or longer, particularly 100 nsec or longer, is a second condition to be judged as phosphorescence, whereas fluorescence shows a shorter luminescence life on the order of several tens nsec or shorter.

[0118] The luminescence material exhibited high phosphorescence quantum yields of 0.15 to 0.9 and short phosphorescence lives of 0.1 to 10 μsec. A short phosphorescence life becomes a condition for causing little energy deactivation and exhibiting an enhanced luminescence efficiency. More specifically if the phosphorescence life is long, the number of triplet state molecules maintained for luminescence is increased, and the deactivation process is liable to occur, thus resulting in a lower luminescence efficiency particularly at the time of a high-current density. The material of the present invention has a relatively short phosphorescence life thus exhibiting a high phosphorescence quantum yield, and is therefore suitable as a luminescence material for an EL device. The present inventors further consider that the improved performance is attributable to the following.

[0119] A difference between a photo-absorption spectrum peak wavelength caused by transition from a single ground state to an excited triplet state and a maximum peak wavelength of luminescence spectrum is generally called a Stokes' shift. The difference in peak wavelength is considered to be caused by a change in energy state of triplet excitons affected by other ground state energy levels. The change in energy state is associated with the Stokes' shift, and a larger amount of the shift generally results in a lowering in maximum luminescence intensity and a broadening of luminescence spectrum leading to a deterioration in monochromaticity of luminescence color. This effect appears particularly remarkably in a red region having a short transition width from the singlet to the triplet.

[0120] For example, as for the isoquinoline-type iridium complexes of the present invention, tris(1-phenylisoquinoline-C²,N)iridium (III) (Example Compound No. 1 in Tables 1 to 23 appearing hereafter; abbreviated as Ir(PiQ)₃), tris[1-(2-thienyl)-isoquinoline-C³,N]iridium (III) (Example Compound No. 24, abbreviated as Ir(tiQ)₃), and tris[1-(9,9-dimethylfluorene-2-yl)isoquinoline-C³,N]iridium (III) (Example Compound 28, abbreviated as Ir(FliQ)₃) exhibited Stokes' shifts of 37 nm, 55 nm and 33 nm, respectively, and relative quantum yields of 0.66, 0.43 and 0.48, respectively.

[0121] On the other hand, as for non-isoquinoline-type red luminescence materials, tris[1-thianaphthene-2-yl)pyridine-C³,N]iridium (III) (abbreviated as Ir(BrP)₃) and tris[1-(thianaphthene-2-yl)-4-trifluoromethylpyridine (abbreviated as Ir(Bt₅CF₃Py)₃) exhibited remarkably longer Stokes' shifts of 132 nm and 85 nm, respectively, and lower relative quantum yields of 0.29 and 0.12, respectively, compared with the compounds of the present invention.

[0122] Even such non-isoquinoline-type red luminescence materials show high quantum yields not achieved by conventional materials, red luminescence materials showing a smaller Stokes' shift, like isoquinoline-type iridium complexes of the present invention, are found to have a tendency of having a still higher quantum yield. A smaller Stokes' shift is considered to provide a larger velocity constant of energy radiation, a shorter phosphorescence life and therefore a higher luminescence efficiency. Based on the above consideration, the introduction of isoquinoline is considered to result in a small Stokes' shift, an enhanced luminescence quantum yield and a better chromaticity.

<<Nomenclature and Structural Expression of Compounds>>

[0123] Now, some explanation is added to the manner of structural identification of a metal coordination compound of the present invention and the manner of allotting atomic position number as a basis therefor with reference to Ir(PiQ)₃ (Example Compound No. 1), for example. The metal coordination compound has a ligand of 1-phenylisoquinoline of which position numbers are allotted as follows:

[0124]

[0125] Accordingly, Ir(PiQ)₃ formed by coordination of three 1-phenylisoquinoline molecules onto iridium with the position-2 carbon atom of the phenyl group and the nitrogen atom of the isoquinoline ring is named as tris(1-phenylisoquinoline-C²,N)iridium (III).

[0126] Ir(PiQ)₃ exhibits a high quantum yield as mentioned above, but it has been also found that Ir(PiQ)₃ provided with an additional substituent shows a further higher quantum yield in a solution or a solid state film. For example, a class of tris[1-alkylphenyl)isoquinoline-C²,N]iridium (III) formed by attaching alkyl substituents at position-4 of the basic ligand skeleton of 1-phenylisoquinoline exhibits still higher relative quantum yields (i.e., quantum yields when Ir(ppy)₃ in a dilute solution in toluene is taken to have a quantum yield of 1). More specifically, the class of compounds have been found to exhibit quantum yields as shown below depending on species of the alkyl substituents. Remarkable increases in quantum yield have been recognized at number of carbon atoms of 4 or more in the subsequent group.

• • [0127] (1) —CH₃=0.64
  • [0128] (2) —C(CH₃)₃=0.7
  • [0129] (3) —C₄H₉=0.82
  • [0130] (4) —C₆H₁₃=0.88
  • [0131] (5) —C₈H₁₇=0.72
    From the above results, the addition of a substituent to the above skeleton to weaken the inter-molecular interaction is found to be effective for increasing the luminescence quantum yield.

[0132] On the other hand, in the case of using resistance heating vacuum deposition using a tungsten boat for device formation, a material having a molecular weight of at most 1000 has been found suitable in view of the device production process characteristic, such as possibility of vacuum deposition at a low current and a high rate.

[0133] More specifically, the above-mentioned class of alkyl chain-added iridium complexes have a tendency of exhibiting a higher vacuum deposition temperature at the time of device formation. The entire molecular weights of thus-alkyl-substituted Ir(PiQ)₃ derivatives are as follows depending on the species of alkyl substituents as follows.

• • [0134] (1) —CH₃=847
  • [0135] (2) —C(CH₃)₃=973
  • [0136] (3) —C₄H₉=973
  • [0137] (4) —C₆H₁₃=1058
  • [0138] (5) —C₈H₁₇=1141

[0139] At the time of resistance heating vacuum deposition at 10⁻⁴ Pa, these materials required necessary currents for vacuum deposition as follows depending an the species of alkyl substituents.

• • [0140] (1) —CH₃=58 amperes
  • [0141] (2) —C(CH₃)₃=61 amperes
  • [0142] (3) —C₄H₉=61 amperes
  • [0143] (4) —C₆H₁₃=64 amperes
  • [0144] (5) —C₈H₁₇=67 amperes

[0145] Further, a metal coordination compound having a substituent of fluorine atom or a polyfluorinated alkyl can weaken the intermolecular interaction owing to fluorine atoms to lower the vacuum deposition temperature, and is advantageous in that a metal coordination compound of a larger molecular weight can be used as a luminescence material without impairing the vacuum deposition characteristic. For example, the substitution of a trifluoromethyl group for one methyl group can lower the vacuum deposition temperature by ca. 1° C. while the molecular weight is rather increased thereby.

[0146] By introducing an isoquinoline skeleton in a metal coordination compound having a structure of a type represented by the above formula (1) or (9), the luminescence wavelength can be adjusted, and it has been found that the metal coordination compound of the present invention wherein the isoquinoline skeleton is bonded to the cyclic group A at its position-1, is unexpectedly advantageous for increasing the luminescence wavelength (i.e., providing red luminescence).

[0147] On the other hand, while a known compound of tetrakis(2-phenylpyridine-C²,N)(μ-dichloro)diiridium (III) does not provide a substantial luminescence spectrum, a metal coordination compound of the formula (7) having introduced an isoquinoline skeleton has exhibited a strong luminescence spectrum. From this fact, it is understood that a metal coordination compound of the formula (7) is also suited as a luminescence material for an EL device.

[0148] Further, by introducing an electron-attractive substituent or an electron-donative substituent to the metal coordination compound of the present invention, it is possible to adjust the luminescence wavelength. Further, by introducing a substituent group, such as an alkoxy group or a polyfluoroalkyl group, having a large electronic effect and also a stereo-scopically large bulk volume, it becomes possible to effect both a control of luminescence wavelength and a suppression of density extinction due to inter-molecular interaction. Further, the introduction of a substituent group having little electronic effect but having a stereoscopically large bulk volume, such as an alkyl group, is considered to be able to suppress the density extraction without changing the luminescence wavelength.

[0149] Further, by replacing one or two CH groups in the isoquinoline ring of a metal coordination compound represented by the formula (1) or (9), the luminescence wavelength can be adjusted without introducing a substituent group.

[0150] Also from the above viewpoints, the metal coordination compound of the present invention is suited as a luminescence material for an organic EL device.

[0151] Further, a thermal stability is an important property for an organic material constituting an organic EL device. The thermal stability seriously affects the production stability at the time of device production and device stability during operation under current supply. For preparation of organic EL devices, a process of vacuum deposition, spin coating or ink jetting is contemplated. Particularly, in the vacuum deposition process, an organic material is subjected to high temperature for certain period for vaporizing the organic material by sublimation or evaporation and is deposited onto the substrate. Accordingly, the thermal stability of a component material is very important.

[0152] Further, also at the time of supplying electricity to the device for causing luminescence, a Joule's heat is locally generated due to passage of a high current. If a component material has a low thermal stability, the material can cause a device deterioration due to such heat. For example, the above-mentioned Ir(PiQ)₃ and bis(1-phenylisoquinoline-C²,N)(acetylacetonato)iridium (III) (Example Compound No. 42, abbreviated as Ir(PiQ)₂acac) exhibited decomposition temperatures of 380° C. and 340° C., respectively, under nitrogen flow, thus providing a substantial difference in decomposition temperature. More specifically, under a certain vacuum deposition condition, Ir(PiQ)₃acac caused an appreciable decomposition in a vacuum deposition chamber, but Ir(PiQ)₃ did not cause appreciable decomposition under the same condition. As a result of measurement of decomposition degree under various conditions of vacuum deposition, Ir(PiQ)₃ acac exhibited lower upper limits in vacuum deposition speed or degree of vacuum in vacuum deposition, thus exhibiting a narrower production margin at the time of mass production. In this way, a material thermal stability seriously affects the productivity.

[0153] In a comparative test, EL devices were prepared from the above-mentioned two luminescence materials through vacuum deposition under decomposition-free condition and subjected to evaluation of luminance deterioration. As a result, when electricity supply was started to provide an initial luminance of 5000 cd/m², Ir(PiQ)₃ and Ir(PiQ)₂ acac exhibited luminance half-attenuation periods in a ratio of ca. 3:1, so that Ir(PiQ)₃ was substantially stable against electricity supply as represented by a longer luminance half-attenuation period. In this way, the thermal stability of a component material is a factor determining the production stability and performance stability of a device, so that a material having a high thermal stability is desired.

[0154] It is believed that the ligand of the present invention, as a result of introduction of isoquinoline skeleton, has a rigid molecular structure, so as to suppress the formation of an excitation-associated molecule resulting in thermal deactivation, thus suppressing energy deactivation due to molecular movement. Further, it is also believed that extinction processes are reduced to result in an improved device performance. In an actual current conduction test, the luminescence material of the present invention, i.e., a metal coordination compound having a ligand comprising an isoquinoline skeleton bonded to a cyclic group A at its 1-position, showed a high stability.

[0155] More specifically, a tris(1-substituted isoquinolyl)-metal coordination compound of n=0 in the formula (3) is generally preferred in view of excellent thermal stability.

[0156] Accordingly, a luminescence material having a luminescence wavelength of long-wavelength region (red luminescence) and a high chemical stability as well as a high luminescence efficiency has not been realized heretofore but can be realized by the luminescence material of the present invention.

[0157] A high-efficiency luminescence device having a layer structure as shown in FIGS. 1(a), (b) and (c) of the present invention is applicable to a product-requiring energy economization or a high luminance. More specifically, the luminescence device is applicable to a display apparatus, an illumination apparatus, a printer light source or a backlight for a luminescence layer display apparatus. As a display apparatus, it allows a flat panel display which is light in weight and provides a highly recognizable display at a low energy consumption. As a printer light source, the luminescence device of the present invention can be used instead of a laser light source of a laser beam printer. For the illumination apparatus or backlight, the energy economization effect according to the present invention can be utilized.

[0158] For the application to a display, a drive system using a thin-film transistor (abbreviated as TFT) drive circuit according to an active matrix-scheme, may be used. Hereinbelow, an embodiment of using a device of the present invention in combination with an active matrix substrate is briefly described with reference to FIG. 4.

[0159] FIG. 4 illustrates an embodiment of panel structure comprising an EL device and drive means. The panel is provided with a scanning signal driver, a data signal driver and a current supply source which are connected to gate selection lines, data signal lines and current supply lines, respectively. At each intersection of the gate selection lines and the data signal lines, a display pixel electrode is disposed. The scanning signal drive sequentially selects the gate selection lines G1, G2, G3 . . . Gn, and in synchronism herewith, picture signals are supplied from the data signal driver to display a printer.

[0160] TFT switching devices are not particularly restricted, and devices of a single crystal-silicon substrate, MIM devices or devices of a-Si type can be easily applied.

[0161] On the ITO electrodes, one or more organic EL layers and a cathode layer are sequentially disposed to provide an organic EL display panel. By driving a display panel including a luminescence layer comprising a luminescence material of the present invention, it becomes possible to provide a display which exhibits a good picture quality and is stable even for a long period display.
