1305800 A7 A7 B7 V. INSTRUCTIONS (彳) FIELD OF THE INVENTION (Please read the note on the back and then fill out this page.) The present invention relates to a layer having an anode, a cathode, and an organic compound containing an electric field applied to emit light (hereinafter referred to as " Organic light-emitting element of organic compound layer"), and light-emitting device using the same. Generally, the luminescence of an organic compound derived from the application of an electric field has luminescence (fluorescence) upon recovery from a singlet excited state to a ground state, and luminescence (phosphorescence) when a ground state is restored from a triplet excited state, and the present invention In particular, it relates to an organic light-emitting element using an organic compound that produces phosphorescence. Further, the light-emitting device in the present specification means an image display device or a light-emitting device in which the light-emitting element is an organic light-emitting element. Further, a module such as an anisotropic conductive film (FPC: flexible printed circuit) or a TAB (automatic tape bonding) tape or a TCP (transport tape package) is attached to the organic light-emitting element, and the TAB tape and the TCP are used. A module in which a printed circuit board is provided at the end, or a module in which an IC (integrated circuit) is directly mounted on an organic light-emitting element by a C 0 G (glass substrate wafer soldering) method is also included in the light-emitting device. Advance Technology The Ministry of Economic Affairs, the Intellectual Property Office, and the Consumer Cooperatives Printed Organic Light-emitting Components are components that emit electric light. The luminescence mechanism is such that an organic compound layer is interposed between the electrodes. When a voltage is applied, the electrons injected from the cathode and the positive holes injected from the anode are recombined in the organic compound layer to form excited molecules (hereinafter referred to as "molecular excitons". ), the molecular excitons release energy and emit light when they return to the ground state. Such an organic light-emitting element is usually formed with a film of an organic compound layer having a submicron degree. And because the organic light-emitting element is the organic compound layer itself, the paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm). One by one -4- 1305800 A7 B7 V. Invention description (2) Light self-luminous component It does not need to be used for backlighting of liquid crystal displays. Therefore, one of the great advantages of the organic light-emitting element is that it can be made extremely light and extremely thin. (Please read the precautions on the back and fill out this page.) Also, for example, in the organic compound layer of about 100 to 200 nm, considering the time from the injection of the carrier to the recombination, consider the organic compound layer. The sub-movement is in the order of tens of nanoseconds, and even if the process of including the carrier is recombined to the illuminating, it can emit light within a microsecond. Therefore, the speed of response is very fast. Further, since the organic light-emitting element is a carrier-injection type light-emitting element, it can be driven by a DC voltage, and noise is less likely to occur. Regarding the driving voltage, the organic compound layer is first formed into a uniform film having a thickness of about 100 nm, and an electrode material having a small barrier to the carrier of the organic compound layer is selected, and a heterostructure (two-layer structure) is further introduced to 5 5 volts can reach a full brightness of 100 new candles per square meter (Document 1: CW Tang and SA

VanSlyke, "Organic electroluminescent diodes", Applied Physics Letters, vol. 51, No.12, 913-915 (19 8 7) ) ° The Ministry of Economic Affairs’ Intellectual Property Bureau’s 8-construction consumer cooperatives are printed because of their lightness and thinness. High-speed responsiveness, DC low-voltage driving and other characteristics, organic light-emitting elements have become the focus of next-generation flat-panel display components. Because it is self-illuminating, it has a wide viewing angle and good visibility, and is approved for use in the display panel of mobile devices.

The luminescence of the organic light-emitting element is the luminescence phenomenon when the molecular excitons return to the ground state. As described above, the molecular excitons formed by the organic compound may have a singlet excited state (S*) and a triplet excited state (T). *). In addition, the statistically produced ratio of the organic light-emitting elements is recognized as S * : T * = 1:3 (Document 2: City Hall 2, "Display Monthly Special Issues Organic EL This paper scale applies the Chinese National Standard (CNS) A4 specification ( 210X297 mm) -5- Ministry of Economic Affairs Intellectual Property Office Staff Consumer Cooperative Printed 1305800 A7 B7 V. Invention Description (3) Display from Basic to Latest Information" (Techno Times), p.28-29) ° However, generally The organic compound has no observation at the room temperature due to the luminescence (phosphorescence) of the triplet excited state (T*), and usually only the observation of the luminescence (fluorescence) from the singlet excited state (S*). This is because the ground state of the organic compound is usually singlet (S 0 ), the spin of the TSQ transfer system is prohibited from shifting, and the s*-So transfer is spin-allowed transfer, that is, usually only the singlet excited state (S *) Helps to emit light, which is the same as organic light-emitting elements. Therefore, the theoretical quantum limit of the internal quantum efficiency of the organic light-emitting element (the ratio of photons generated to the injected carrier) is based on S * ·· T * =1 : 3 is 25%. Further, not all of the generated light is emitted outward, and part of the light cannot be emitted due to the inherent refractive index of the organic light-emitting element constituent material (organic compound layer material, electrode material) or the substrate material. The ratio of the generated light is called the light emission efficiency, and the organic light-emitting element including the glass substrate has an emission efficiency of about 20%. For the above reasons, even if all the injected carriers form molecular excitons, the ratio of the number of photons injected to the outside will be 25% x 20% = 5 %. That is, even if all the carriers are recombined, only 5% of them are expected to be emitted. In recent years, the energy released from the triplet excited state (T*) to the ground state (hereinafter referred to as "triplet state excitation energy") can be converted into luminescent organic light-emitting elements successively, and its luminous efficiency is high.

Invention description (5) (Please read the note on the back and fill out this page) As shown in documents 3 to 5, An organic light-emitting element that converts triplet excitation energy into a light-emitting organic compound (hereinafter referred to as "triplet light-emitting material") can achieve higher external quantum efficiency than before. And if the external quantum efficiency is increased, the luminance of the light is also increased. Therefore, an organic light-emitting element using a triplet light-emitting material is required to achieve high-brightness light emission and high light-emitting efficiency, and its development ratio is bound to increase in the future. Problems to be Solved by the Invention However, since both platinum and rhodium are so-called noble metals, platinum-conjugates and rhodium complexes used therein are also expensive, and it is predicted that this will be disadvantageous for cost reduction. Moreover, platinum and rhodium are rare metals and are difficult to supply for mass production. The luminescence of the above complex is green, that is, the wavelength is in the middle of the visible range. When the platinum complex is used as a dopant, red light having a better color purity can be emitted. However, when the concentration is low, the main material also emits light to deteriorate the color purity, and when the concentration is high, the concentration is extinguished, and the luminous efficiency is lowered. That is to say, the high-purity red and blue high-efficiency luminescence cannot be obtained from an organic light-emitting element that can convert triplet excitation energy into luminescence. Printed by the Intellectual Property Office of the Ministry of Economic Affairs and the Consumer Cooperatives of the Ministry of Economic Affairs, and the organometallic complex of the above-mentioned ruthenium complex with the central metal and the ligand benzene ring system directly combined with σ, the productivity is not good because of the poor time-consuming yield of synthesis. . From the viewpoint of productivity, the Werner complex of tris-quinoline aluminum (hereinafter referred to as "A 1 d3j"), which is commonly used in organic light-emitting elements, is generally considered to be effective. Therefore, if it is considered to be red, green, and used in future production. The blue-emitting full-color flat-panel display must achieve a high external volume such as uranium complex and bismuth complex.

INSTRUCTIONS (6) Sub-efficiency, and mass production of low-cost, high-purity luminescent materials. (Please read the notes on the back and fill out this page.) Based on the above, in addition to the existing i-compound, 铳In addition to the complex compound, the development of triplet luminescent materials is imperative. Therefore, the object of the present invention is to provide a triplet luminescent material which is cheaper than in the past, and provides the use of the material to have a luminous efficiency superior to that of the prior art. An organic light-emitting device which is inexpensively produced. Further, a light-emitting efficiency organic light-emitting device which is obtained by using the present invention, a light-emitting device which is bright, consumes less power, and which is inexpensive, and an electric appliance using the same are provided. Means for Solving the Problem The inventors of the present invention have repeatedly deliberately solved the above problems by using a phosphorescent tungsten complex. The present invention is composed of an anode, a cathode, and an organic compound layer provided between the anode and the cathode. The organic light-emitting device characterized in that the organic compound layer has a metal complex which contains a ligand of an aromatic ring and a tungsten-centered metal. The Ministry of Economic Affairs, Intellectual Property Office, employee consumption cooperative prints, for example, the above The metal complex is characterized by containing the following general formula (1) (Ri to R8 represents a hydrogen atom or a halogen atom, or any of an alkyl group, an alkoxy group, or an aryl group. n represents an integer of 1 to 4.)

INSTRUCTIONS (8) Provide bright, low-power, low-cost lighting devices, and use The present invention also includes a light-emitting device and an electric appliance using the same. (Please read the back note and then fill out this page.) Embodiments of the Invention The present inventors have focused on PL (light-excited light; In order to stimulate the light source of the source, it is known that the heavy atom effect is to introduce a heavy atom into the molecule of the luminescent substance, or to have a heavy atom in the surrounding environment such as a solvent in which the luminescent substance is dissolved, and to expand the spin orbit. Interaction, the phenomenon of inter-state interleaving (S*-T*) and phosphorescence (τ*-S〇) is prohibited. In this case, heavy atom means having a large nuclear load (atomic order, which is equivalent to the nucleus). Atomic number of atoms The effectiveness depends on the intrinsic 値 spin-orbital binding constant of each atom (the heavier the atom is, the larger the atom is), so the atom that can be used to induce the effect of heavy atom should be limited to a certain extent. Specifically, platinum, ruthenium The second transition series of the steroids is preferably an atom. For this reason, the platinum complex and the ruthenium complex are effective triplet luminescent materials, and heavy metals such as platinum and rhodium are generally expensive. The Intellectual Property Office employee consumption cooperative is printed, so the inventors first focused on the use of tungsten as a heavy atom. Tungsten belongs to the transition metal of the third transition series element, and the most expensive inexpensive metal on the earth meets the needs of the present invention. The atomic order of platinum is 7.8, and the atomic order of yttrium is 7,7. Compared with this, the atomic order of tungsten is substantially the same, and the possibility of heavy atomic effects equivalent to uranium and thorium is high. In fact, transition metal Among the carbonyl complex M (C0) 5 (NH (C 2 Η 5 ) 2 ) (M=Cr, Mo, W), only the paper scale applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) - 11 - 1305800 A7 B7 V. Invention (9) When the core metal is tungsten, there is a cross-state interleaving (S ! - T i ) and phosphorescence (Ti-S〇) promotion observation of the heavy atom effect (Record 6: Inoue Kiyoshi, Takagi Kyuhiko, Sasaki Masako , Park Chung-sheng, "Basic Chemistry Course Chemicals" (Jiushan), P.74-76). Secondly, it is necessary to discuss the coordination group of the central metal tungsten. The tungsten-containing metal complex (hereinafter referred to as "tungsten complex") disclosed in the present invention can be used for an organic light-emitting element, and its electrical and chemical stability is a necessary condition. It must have carrier transportability as much as possible. Based on these viewpoints, it is preferred to use a tethered ligand as a ligand. This is because, compared to the monodentate coordination of the carbonyl complex as in Document 6, the complex which forms the clamp ring is relatively stable (clamping effect). Further, among the ligands forming the clamp ring, a ligand having an aromatic ring (i.e., an aromatic compound) is not uncommon, and a complex using such a ligand often has carrier transportability. One of the reasons. Based on the above, the present invention contemplates a metal complex having a tungsten-centered metal and a chelating ligand containing an aromatic ring, which is used for an organic light-emitting element. There are aromatic ring clamp ligands, phosphorescent tungsten complexes, and zero-valent tungsten complexes with phenanthroline ligands are known (Document 7: Kathleen A. Rawlins and Alistair Lees, "A TUNGSTEN ORGANOMETALLIC COMPLEX AS A SPECTROSCOPIC PROBE OF ACRYLATE POLYMERIZATION IN THIN FILM", Polym. Prepr., 647-648 (1996)). Therefore, the present invention can be used in the form of a tungsten complex containing the structure of the general formula (1). However, there is only one phenanthroline ligand in the literature 7, and the other ligands are carbonyl basic paper scales applicable to the Chinese National Standard (CNS) A4 specification (2I0X297 mm) (please read the notes on the back and fill out this page) - 'β Ministry of Economic Affairs Intellectual Property Bureau employee consumption cooperative printing -12- 1305800 A7 B7 V. Invention description (1〇). It is preferred that the present invention be such that the carbonyl group is substituted with a ligand substituent. For example, a tungsten complex of the following formula (3) can be considered.

2,2'-bipyridyl can also be used as the same ligand. That is, a tungsten complex containing the structure of the general formula (2). For example, consider the tungsten complex of formula (4) below (please read the notes on the back and fill out this page)

Printed by the Intellectual Property Office of the Ministry of Economic Affairs, the Consumer Cooperative of the Ministry of Economic Affairs uses the simple and productive Werner-type complex, but the organic metal complex directly combined with the carbon atom of the central metal and the ligand. There are improvements in application features. This has been evident in the above-mentioned oxime complexes. Next, the form of the organic light-emitting element at the time of production will be described. When the organic compound disclosed in the present invention is used as a light-emitting material of an organic light-emitting element, the paper can be used as a light-emitting material (CNS) A4j^ (21GX297 mm) ---~~ — -13- 1305800 A7 B7 5. The invention description (n) is divided into two categories. The first one is used as the luminescent layer in Fig. 1(a), and the other is used as the doping in Fig. 1(b). (Please read the precautions on the back and fill out this page.) Figure 1 (a) shows the organic compound disclosed in the present invention as an electron transporting light-emitting layer (single-heterostructure), but it can also be used as a positive-porous transport layer. A light-emitting layer (double heterophase structure) between electron transport layers. Further, Fig. 1(b) is characterized in that the organic compound disclosed in the present invention is doped to the electron transport layer, but may be doped to the positive hole transport layer. Further, in the first embodiment, the anode is provided on the substrate, but the cathode may be provided on the substrate. However, when the tungsten complex disclosed in the present invention introduces various substituents, the carrier transportability may be impaired. In this case, the method of using the dopant as in Fig. 1(b) is preferable to the method of using the light-emitting layer as shown in Fig. 1(a). Further, an inorganic compound may be introduced into the organic light-emitting device. For example, it is conceivable to introduce an inorganic compound as a positive hole injection layer which is in contact with the anode or an electron injection layer which is in contact with the cathode.

In particular, the luminescence spectrum of the host material is preferred when it is added to the absorption spectrum of the organic compound of the present invention. In the present embodiment, the organic compound of the present invention is added to the positive hole transport layer, but may be added to the electron transport layer or the light-emitting layer.

Specifically, a glass substrate, a quartz substrate, a crystallized glass substrate, or a plastic substrate (including a plastic film) can be used. The substrate 310 includes an insulating film provided on the surface. A pixel portion 31 1 and a drive circuit 3 1 2 are provided on the substrate 310. First, the pixel portion 3 1 1 will be described. The pixel portion 311 is an area for image display. A plurality of pixels are present on the substrate, and each pixel is provided with a TFT (hereinafter referred to as "current control TFT") 302 for controlling current flowing through the organic light emitting element, a pixel electrode (anode) 303, an organic compound layer 304, and a cathode 305. Further, although Fig. 3(a) shows only the current controlling TFT, a TFT for controlling the voltage applied to the gate of the current controlling TFT (hereinafter referred to as "switching TFT") is provided. Printed by the Intellectual Property Office of the Ministry of Economic Affairs, the Consumer Cooperative, the current control TFT3 0 2 is preferably a P-channel TFT. The n-channel type TFT is indispensable, but when the current is connected to the anode of the organic light-emitting element as shown in Fig. 3, the power consumption of the p-channel type TFT can be lowered. However, the exchange of T F T can be performed with n-channel type T F T or p-channel type T F. Further, the drain of the current controlling TFT 300 is electrically connected to the pixel electrode 300. In this embodiment, the working function is 4 .  5 to 5 .  The conductive material of 5 electron volts is used as the material of the pixel electrode 3 0 3 , and the pixel electrode 303 has the function of the anode of the organic light-emitting element.

The material of the cathode 3 0 5 should use the work function 2 .  5 to 3 .  Conductive material of 5 electron volts. The cathode 3 0 5 is typically a conductive film containing an alkali metal element or an alkaline earth metal element, an aluminum-containing conductive film, or a conductive film laminated thereon, such as a silver or a silver. The layer formed by the pixel electrode 300, the organic compound layer 3 〇 4 and the cathode 305 is covered with a protective film 306. The protective film 3 0 6 is used to insulate oxygen and water. The material of the protective film 306 is tantalum nitride, lanthanum oxide, aluminum oxide, oxidized giant or carbon (specifically diamond-like carbon). Next, the drive circuit 3 1 2 will be described. The driving circuit 3 1 2 is for controlling the timing of the signals (gate signal and data signal) transmitted to the pixel portion 31 1 , and is provided with a shift register, a buffer, a latch, and an analog switch (transfer gate) Or level shifter. Figure 3 (a) shows the N-channel type T F Τ 3 0 7 and the ρ-channel type T F Τ 3 0 8 as the CMO S circuit of the basic unit of these circuits. The Ministry of Economic Affairs, the Intellectual Property Office, the employee consortium, and the circuit configuration of the shift register, buffer, latch, analog switch (transfer gate) or level shifter can be known. In Fig. 3, the pixel portion 31 and the driver circuit 31 are provided on the same substrate. However, the driver circuit 312 may not be provided, and the 1C and the LSI may be electrically connected. Further, in Fig. 3, the pixel electrode (anode) 3 0 3 is electrically connected to the current control T F T 3 0 2 , but may be a structure in which the cathode is connected to the current control τ F T . At this time, a pixel electrode can be formed using a material like the cathode 305, and a cathode can be formed by a material such as a pixel electrode (anode) 305. This paper size is applicable to China National Standard (CNS) A4 specification (210X297 mm) -18- 1305800 A7 B7 5. Inventive Note (16), it is better to use η channel type T F T as current control T F T . (Read the first note on the back side and fill in this page.) The light-emitting device of Fig. 3(a) is formed by forming the wiring electrode 3 0 3 after forming the pixel electrode 3 0 3 . In this case, the pixel electrode 3 0 3 may be Causes the surface to be uneven. Since the organic light-emitting element is a current-driven element, the surface unevenness characteristic of the pixel electrode 300 is also deteriorated. Therefore, a light-emitting device in which the pixel electrode 300 is formed after the wiring 309 is formed as in Fig. 3(b) is also considered. At this time, compared with the structure of Fig. 3(a), the current injection property by the pixel electrode 300 should be improved. Further, in Fig. 3, each of the pixels provided in the pixel portion 311 is separated by the obliquely-shaped bank structure 310. Alternatively, the bank structure may be changed to, for example, a reversed shape, so that the bank structure is not in contact with the pixel electrode. An example of this is shown in Figure 4. The Ministry of Economic Affairs, Intellectual Property Office, and the Consumer Cooperatives Printing Bag. Figure 4 shows the wiring and the partitioning unit 3 1 0 with the wiring as the partition. The wiring of FIG. 4 and the shape of the partition portion 31 (the structure having a crucible) can be formed by laminating a metal constituting the wiring and a material having a low etching rate (for example, a metal nitride). This shape prevents the short circuit of the pixel electrode 3 0 3 and the wiring and the cathode 305. In Fig. 4, unlike the conventional active matrix type light-emitting device, the cathodes of the pixels are arranged in a strip shape (like the cathode of the passive matrix). Further, Fig. 5(a) shows an example in which an effective electrode structure is introduced into an active matrix type light-emitting device when a positive hole injection region is formed of a conductive polymer material. Fig. 5(a) is a cross-sectional view, and Fig. 5(b) is a plan view showing the structure of each pixel electrode.
