Description

201037828 VI. Description of the Invention: [Technical Field to Which the Invention Is Ascribed] The present invention relates to a display device. In particular, it relates to a display device including an element having pixels of R, G, and B and emitting color light, and a color filter. [Prior Art] In recent years, CRT (Cathode Ray Tube) display, fluorescent display tube display, field emission type display, and electric display are used as display panels for various electronic devices including large-sized wall-mounted televisions. Electronic displays such as light-emitting displays and liquid crystal displays, and their demand is increasing, and the requirements for improving the image quality thereof are becoming higher and higher. As a method of full coloring, a method of combining a backlight that emits white light and a color filter represented by a liquid crystal display device is known, but light of three primary colors of blue, green, and red is used in each pixel. The development of high-quality images in the form of light-emitting elements has also become increasingly popular. Examples of the light-emitting element used in the pixel include an organic electroluminescence element (organic EL element··0rganic Electr〇_Luminescence deyices). The organic EL device is a light-emitting device having a structure in which a plurality of thin organic layers are sandwiched between a negative electrode and a positive electrode, and a hole is injected into the organic layer from the positive electrode, and an electron is injected into the organic layer from the negative electrode. The luminescence center of the luminescent material in the organic layer is excited by the recombination energy of the hole and the electron recombining with the organic layer, and the light emitted by the luminescent material from the excited state to the ground state is utilized. The organic EL device has characteristics such as self-luminescence and high-speed responsiveness, and is excellent in visibility, ultra-thin and lightweight, and has excellent high-speed responsiveness and animated display performance. Therefore, the industry is investigating its application to full-shape. Thousands of displays. In particular, a two-layer type (stacked type) organic EL element in which an organic thin film (hole transport layer) that transmits a hole and an electron transporting organic thin film (electron transport layer) are laminated (see c·w) Tang and SA VanSlyke, Applied Physics Letters vol 51 913 (10) The organic anal element is attracting attention as a large-area light-emitting element capable of emitting light with a low power of 1 〇v or less. The three-color luminescence method in which the organic EL elements of the light (B), the green (6), and the red (W) are disposed on the substrate is preferable in terms of energy saving, in addition to image quality and color reproduction, and is organic. In the three-color illuminating method, the organic rainbow element itself can emit various colors of light. However, in order to prevent external light, the three-color illuminating method does not use a color glazing sheet. The reflection caused by the reflection is a decrease in the contrast of the display, and a method of combining the color light-emitting sheets corresponding to the respective illuminating colors is proposed, and a method using the micro-cavity structure is also proposed (refer to Japanese Patent Laid-Open No. 2〇〇3_8). Japanese Patent Publication No. 6358. The wavelength of light which increases the intensity in the microcavity structure can be changed, for example, by changing the optical path length of the microcavity structure. Therefore, it is necessary to appropriately set the micro color in each color layer of the color filter. The optical path length of the cavity structure allows the wavelength of the maximum intensity of light to be consistent with the preferred wavelength for brightness and color reproduction. In full color displays, previously, the color reproducibility of display devices has increased with π. The degree of improvement is in a mutually eclectic relationship, and the industry has long expected to cope with the coexistence of the two properties as the main performance of the display device. 143898.doc 201037828 also requires a good perspective from a wider perspective. In the observation of the flat panel display, the image quality does not change.

If a technique in which a hunger element and a color filter using a microcavity structure are combined is used, high color reproducibility and high degree of sub-existence can be achieved for the above reasons. However, in the organic embossing device using the light source of the microcavity structure, there is a problem that the image observed from the oblique direction is significantly darker than the image observed from the normal direction. In addition, it is pointed out that if the image is observed from the normal direction and then observed from the oblique direction, the color tone changes. The industry expects to improve this. With regard to the improvement of the dependence of the observation direction, there has been proposed an improvement from the structural surface of the device (refer to Japanese Laid-Open Patent Publication No. 2007-27042), and the effect thereof is shown. However, these methods all lead to complication of the device, resulting in high cost, so the industry expects an improvement in an easier way. On the other hand, in the color filter type organic EL display device, a color filter material developed for a liquid crystal display can be used. In the blue (B), green (6), red, and 3 primary color pixels, as the pigment used in the green (9) pixel, the C I. pigment green core is often used. It is considered that the pigment is promoted by miniaturization. It is advantageous in terms of transmittance to obtain high luminance, but it is understood that the pigment has not yet reached a sufficient level for the coexistence of high color reproducibility and high luminance in an organic display device. Further, the color filters of the three primary colors are usually formed by the photolithography method, but it is necessary to pattern the respective colors. Therefore, the number of steps is complicated and the yield is lowered. Therefore, the industry is looking forward to the emergence of a color light-emitting sheet that combines the high color reproducibility and the high brightness of the organic display device 143898.doc 201037828 with a simple method. The company is trying to make an attempt to improve the contrast and sound station color chromaticity by using a filter that absorbs light of a wavelength region without using a filter in the display device (see Japanese Patent Special Edition). Japanese Patent Publication No. 2003-157017, however, the filter is not a substitute for the light lithography method, and in particular, the study of the light source for the three primary colors has not been performed so far. [Problem to be Solved by the Invention] An object of the present invention which has been made in view of the above problems is to provide a display device which is simple in structure, can maintain color reproducibility, and can achieve high luminance. Further, another object of the present invention is to provide a display device in which the observation direction dependency is small even when an organic EL element is used. [Technical means for solving the problem] The inventors of the present invention have made diligent research and development, and as a result, it has been found that by combining a light-emitting element that emits R, G, and B light separately with a color light-emitting sheet having a specific absorption spectrum, it is possible to realize - A display device which is non-destructive in color reproducibility and has a small viewing direction dependency, thereby completing the present invention in a more convenient manner than before.

According to the present invention, it has been found that a light source of a 3* & illuminating type is combined with a filter of a kind or a ruthenium having a specific absorption, thereby producing a property superior to the previous filter. It can be seen that a higher brightness can be obtained by a simpler configuration, and a manufacturing process is also simplified. X, according to the configuration of the present invention, it is known that a significant effect is particularly improved in the observation direction dependency. Moreover, the improvement of the observation direction dependence of the previous problem has been successfully achieved by a simpler method. The reason why the above effect is obtained by the constitution of the present invention is not determined, and it can be presumed as follows. That is, it is generally considered that the light source of the three primary colors is used. in, It is important to ensure the reproducibility of the color shirt. It is important to separate the wavelength between the adjacent tones of the spectral sensitivity of the human eye. It is presumed that the microscopic space 15 which becomes the cause of the observation direction depends on the increase in the direction due to multiple interference. The partial wavelength of the stronger chopping wave is close to the wavelength necessary for ensuring the above-described color reproducibility, and therefore, the sensitivity is improved by the sensitivity for improving the brightness without deteriorating the color reproduction; the photoreceptor can maintain color reproducibility. At the same time, the brightness is increased and the observation direction dependence is lowered. [Effect of the Invention] According to the present invention, it is possible to provide an organic display device which achieves high luminance without reducing the color reproducibility of the image by a simple configuration. Further, the present invention can provide a display device in which the observation direction dependence is small even when the organic EL element is used 143898.doc 201037828. [Embodiment] The following is used in the present invention. The color filter is described in the prior art. The color filter in the conventional liquid crystal display device or the like is used to make only the light corresponding to any of R, G, and B. On the other hand, in the case of a color filter used in a display device using three primary color light-emitting elements, light of two or all of R, G, and B is transmitted and cut off. The band that is not required can perform the same function as the previous color filter with a color pattern suitable for three colors. However, since the spectral sensitivity of the human eye cannot be clearly separated for R, G, and B, it is necessary. Accurately absorb the two colors adjacent to the color matching function in the form of an expandable color reproduction area. Moreover, if excessively absorbed to the extent that the light that needs to be emitted is also absorbed, the brightness is lowered and the quality is impaired. The color filter used in the above display device having three color light-emitting elements must have sensitive absorption in a specific wavelength band. The color filter used in the display element of the present invention has an extremely high optical density in the range of 475 nm to 525 nm and/or 55 〇 nm to 62 〇 nm. The former is the wavelength required for the separation of blue and green, and the latter is the wavelength required for green and red, and both are preferred wavelengths for reducing the viewing direction dependence of the display device. Further, the color filter of the present invention has any of the following features in addition to the characteristic of having a maximum absorption value in the specific wavelength region. Hereinafter, a color filter having such characteristics is sometimes referred to as a specific color filter. I43898.doc •10- 201037828 (1) When the maximum value of optical density is in the range of 475 nm to 525 nm, the ratio of the optical density at a wavelength of 450 nm to the maximum value of the optical density is 15% or less. Further, the ratio of the optical density at a wavelength of 550 nm to the maximum value of the optical density is 10% or less. (2) When the maximum value of optical density is in the range of 550 nm to 620 nm, the ratio of the optical density at a wavelength of 500 nm and a wavelength of 630 nm to the maximum value of the optical density is 12% or less. The ratio of the optical density specified in the above (1) and (2) exceeds the predetermined value, that is, the optical density difference between the two becomes smaller, and the transmittance of each color becomes worse than the previous transmittance, so it is necessary to suppress Below the above values. In the above (1), when the color light-emitting sheet has a maximum value of optical density in the range of 475 nm to 525 nm, the wavelength region exhibiting the maximum value of the optical density is preferably in the range of 480 nm to 520 nm. Especially, it is in the range of 490 nm to 5 15 nm. At this time, the ratio of the optical density at a wavelength of 450 nm to the extremely large value of the optical density is preferably 15% or less, more preferably 13% or less. The ratio of the optical density at a wavelength of 550 nm to the maximum value of the optical density is preferably 10% or less, more preferably 5% or less, and particularly preferably 2% or less. In the above (2), when the color filter has a maximum value of optical density in the range of 550 nm to 620 nm, the wavelength region exhibiting the maximum value of the optical density is preferably in the range of 560 nm to 610 nm. Especially, it is in the range of 570 nm to 600 nm. At this time, the ratio of the optical density at 500 nm and 630 nm to the maximum value is preferably 12% or less, more preferably 10% or less. 143898.doc 201037828 As described above, it is preferable to have a sharp peak of optical density in a specific wavelength region in any case, and it is also preferable to use both the characteristics of both 〇) and (2). A color dipole having characteristics and having a maximum of two optical densities in a predetermined region. The color filter of the present invention (hereinafter referred to as a filter layer as appropriate) uses a colored material in order to have a desired optical density in an absorption wavelength. The colored material may be a dye or a pigment, but in terms of ease of adjustment, a dye is preferred. Any dye may be used for the above purpose, but as a preferred dye for controlling the absorption of the 0 spectrum, a squarylium dye, a azomethine dye, an eyanine may be mentioned. Dye, xonol, azo dye, arylene plus dye, xanthene dye or mercyanine dye. In the light-receiving sheet layer, the dyes as described above may be used singly or in combination of two or more. Further, it is also possible to use a dye having an absorption maximum in a range of wavelengths of 475 nm and 525 nm and a range of 55 Å to 62 〇 nm in the light-passing sheet layer. By using such a dyeing machine, a color filter having the above two characteristics (1) and (2) can be prepared. It is particularly preferable to use a dye in an associated state for obtaining the sensitive absorption as described above. The dye in the 0 state forms the so-called J-band, and thus exhibits a steep peak of the light-receiving name. The association of dyes with the j-band is described in the literature (for example, hotographic Science and Engineering Vol. 18, No. 323-335 (1974)). In the dye of the associative state, the state of association dyeing 143898.doc •12· 201037828 The absorption maximum of the material is further shifted to the wavelength side longer than the absorption maximum of the dye in the solution state. Therefore, it is possible to easily judge whether the dye contained in the filter layer is in an associative state or a non-associated state by measuring the absorption maximum value. • There are also compounds in dyes that form aggregates as long as they are dissolved in water. J and 7 are added to a solution of the dye to add gelatin or a salt (for example, gasification lock chlorinated money, sodium chloride) to form aggregates. Particularly preferred is a method of adding gelatin to an aqueous solution of the dye. The aggregate of the dye can also be formed as a solid fine particle dispersion of the dye. In order to form a solid fine particle, a known dispersing machine can be used. Examples of the dispersing machine include a ball mill, a vibrating mill, a planetary ball mill, a sand mill, a colloid mill, a jet mill, and a roll mill. Among them, a medium dispersing machine of a vertical type or a horizontal type can be preferably used, for example, a medium dispersing machine described in the specification of Japanese Patent Laid-Open No. Hei 52-9 and No. 88/074794. The dispersion of Ο (iv) can also be carried out in the presence of a suitable medium such as water, alcohol or solvent. When dispersing, it is preferred to use a surfactant for dispersion. As the surfactant for dispersion, an anionic surfactant can be preferably used (for example, those described in JP-A-52-92716 and JP-A-88/074794). An anionic polymer, a nonionic surfactant or a cationic surfactant may also be used as needed. It is also possible to obtain a fine particle-like powder by dissolving the dye in a suitable solvent and adding a straight solvent. In this case, the surfactant can also be used in the above-mentioned 143898.doc -13- 201037828. Further, the microcrystals of the dye can be precipitated by adjusting the solution, and the crystallites obtained by precipitation are also aggregates of the dye. When the dye in the associative state is a microparticle (or microcrystal), the flat particle is preferably G.G1 „μπι. The average particle size of the dye particle or crystallite is used from the scanning electron microscope. The value obtained by averaging the 500 measured values in the captured image is used as a dye for preparing a color filter having an absorption maximum value in a wavelength region of 475 nm to 525 nm, as long as it is 45 〇. The ratio of the optical density at nm to the maximum value is 15% or less, and the optical of 55 〇 nm T: a dye having a ratio of the degree to the maximum value of 5% or less can be used for any dye. As long as it is a dye that satisfies this condition, a plurality of dyes may be used in combination. The dye is preferably a dye having a full width at half maximum (a half of the absorbance of the absorption maximum and a width of the wavelength region of the luminosity) of nm or less, more preferably 40 nm or less, and even more preferably 35 nm. Below, the best is below 30 nm. Specific examples of the dye type include a cyanine dye, an oxonium dye, an arylene dye, a merocyanine dye, a squaraine dye, a methine azo dye, an azo dye, or a ruthenium P star dye. In particular, as a preferred dye, a dye selected from the group consisting of compounds represented by the following formula, formula and formula (ΠΙ) can be cited.

The light-emitting layer 13B of the organic EL light-emitting element 10B has a thickness of, for example, about 30 nm, and contains 4,4·_bis(2,2i-diphenylvinyl)biphenyl (DPVBi). The electron-transporting layer 13c of the organic light-emitting element 10 has a thickness of, for example, about 30 nm and contains Aiq3. Ο Fig. 3 shows an enlarged view of the configuration of the organic layer 13 in the organic EL light-emitting element 1 〇G. The organic layer 13 of the organic EL light-emitting element i〇G has a structure in which a hole transport layer 13A and a light-emitting layer 13B are laminated in this order from the side of the first electrode 12. The hole transport layer 13A doubles as a hole injection layer, and the light-emitting layer 13B doubles as an electron transport layer. The hole transport layer 13A of the organic EL light-emitting element 10G has, for example, a thickness of about 5 〇 nm and includes a-NPD. In the case of the light-emitting layer 13B of the organic EL light-emitting element i〇G, the thickness Q is about 60 nm, and it is contained in Alq3 and mixed with i% by volume of coumarin 6 (C6; Coumarin 6). The second electrode 14 shown in Figs. 1 to 3 has a function as a semi-transmissive reflective layer. In other words, the organic EL light-emitting elements 1 〇R, 1 〇G, and 10B have the end surface on the light-emitting layer 13B side of the first electrode 丨2 as the ith end portion ρι, and the end surface on the light-emitting layer 13B side of the second electrode 14 as the first surface. In the second end portion P2, the organic layer 13 serves as a resonance portion, and the light generated in the light-emitting layer 13B resonates and is emitted from the side of the second end portion p2. If the resonator structure is as described above, the light generated in the light-emitting layer 13B generates multiple interferences, and functions as a narrow-band filter 143898.doc -41 - 201037828, whereby half of the spectrum of the emitted light It is preferred because the height and width are reduced and the color purity is improved. Further, 'the light can be attenuated by the interference of the self-sealing panel 2〇 by multiple interferences', and the organic EL light-emitting elements 10R, 1 can be made by a combination with the color filter 22 (refer to FIG. 1) described below. The reflectance of light outside G, 1〇B becomes extremely small', so it is preferable. The protective film 15 shown in FIG. 1 has, for example, a thickness of 5 〇〇 nm or more, 1 〇, or less than 〇〇〇 nm, which is a passivation film containing a transparent dielectric. The protective film 15 contains, for example, yttrium oxide (Si〇2), tantalum nitride (SiN), or the like. As shown in Fig. 1, the sealing panel 2A has a sealing substrate 21 which is disposed on the side of the second electrode 14 of the driving panel 1A and which seals the organic rainbow light-emitting elements, 10G, and 10B together with the adhesive layer 3'. The sealing substrate 21 includes a material such as glass transparent to light generated in the organic EL light-emitting elements 1011, 1〇G, and 1B. For example, a color filter 22 is provided on the sealing substrate 21, which emits light generated by the organic EL light-emitting elements i〇r, i〇G, and 10B, and is absorbed by the organic EL light-emitting elements 10R, i〇G. , 10B, and the wiring between the wires are reflected outside, thereby improving contrast. The color filter 22 may be provided on either side of the sealing substrate 21, but is preferably provided on the side of the driving panel 1A. The reason for this is that the color filter 22 can be prevented from being exposed on the surface and protected by the adhesive layer 3 . The color filter 22 has the red color filter 22R, the green color filter 22G, and the blue color filter 22B'. These are arranged in order corresponding to the organic EL light-emitting elements i〇r, i〇G, and 10B. The red color filter 22R, the green color filter 22G, and the blue color filter 22B are divided into 143898.doc • 42· 201037828, for example, in a rectangular shape and without a gap. The red color filter 22R, the green color filter 22G, and the blue color filter 22A respectively contain a resin mixed with a pigment and are adjusted by selecting a pigment to transmit light as a target red, green or blue wavelength band. Rate 胄 high n light segment of the light; become lower. Ο 〇 Figures 4Α to 4Β and Figs. 5Α to 5Β show the manufacturing method of the display device in order of steps. First, as shown in FIG. 4A, the first electrode 12 including the above material is formed on the driving substrate U including the above material by, for example, direct current (four), and then selectively performed using, for example, lithography. The film is patterned into a predetermined shape. Thereafter, as shown in FIG. 4A, the organic layer 13 (including the hole transport layer 13A, the light-emitting layer UB, and/or the electron transport layer 13C) having the above-described thickness and material is sequentially formed by, for example, a vapor deposition method. The second electrode 14 is formed with organic light-emitting elements urn, 1 () G, _ as shown in FIGS. 2 and 3, respectively. Thereafter, the protective film 15 is formed on the second electrode 14 as needed. Thereby, the drive panel 1A is formed. Fig. 4B shows a color filter having a coloring pattern of r, g, b formed by the prior method. For example, a material of the red filter or the light sheet 22R is applied by a spin coating method or the like (in the present embodiment, a coloring photosensitive composition described later is used), and the photolithography technique is used for the sealing substrate. Calcination after patterning ' II This forms a red filter 22R. Then, the blue color filter 22B and the green color filter 22G are sequentially formed in the same manner as the formation of the red color filter 22R, thereby forming the sealing panel 2 having the r, G, and B coloring patterns shown in Fig. 4b. The order of formation of red filter, light film, blue calender and green calender is 143898.doc •43· 201037828 Arbitrary setting. From the above, it is known that in the previous step, the step of patterning 'calcination only repeats the number of tones. According to the present invention, the one-tone light-passing sheet can have both the previous two colors', so that the number of steps of the portion can be reduced. After the sealing panel 20 and the driving panel 1 are formed, as shown in Fig. 5A, an adhesive layer 30 is formed on the protective film 15. Thereafter, as shown in Fig. 5B, the driving panel 1A is bonded to the sealing panel 2A via the subsequent layer 30. At this time, it is preferable that the side of the sealing panel 20 on the side where the color filter 22 is formed is disposed opposite to the driving panel 10. By driving the driving panel 1A and the sealing panel 2 in the above manner, the display device shown in Figs. 1 to 3 is completed. In the display device, when a predetermined voltage is applied between the first electrode 12 and the second electrode 14, a current is injected into the light-emitting layer 13B, and the hole and the electron are again bonded, whereby the light-emitting layer 13B is mainly used. The interface causes luminescence. This light is multi-reflected between the first electrode 12 and the second electrode 14, and is transmitted through the second electrode 14, the protective layer 15, the color filter 22, and the sealing substrate 21. At this time, the external light is incident from the side of the substrate 2 1 for sealing, but the external light other than the resonance wavelength is absorbed by the color filter 22' and is attenuated by the multiple interference in the organic EL light-emitting elements 10R, 10G, and 10B. On the other hand, light other than the resonance wavelength passes through the color filter 22 and enters the organic EL light-emitting elements 10R, 10G, and 10B, and is mainly reflected by the second electrode 14 and the first electrode 12. However, in the present embodiment, the side of the first end portion P1, that is, the side of the first electrode 12 and the second end portion P2, that is, the reflected light of the external light in the second electrode 14 is configured as follows. The intensity and phase were adjusted so that the reflectance in the organic EL light-emitting elements 10R, 10G, and 10B became 20. /. In the following, therefore, the reflected light emitted from the external light-reversing substrate 21 is extremely limited to 143898.doc-44-201037828. Therefore, the impact of shooting or location is reduced. Although the first embodiment of the present invention is described in the first embodiment, the present invention is not limited to the above embodiment, and various modifications can be made. For example, the materials of the respective layers described in the above-described embodiments, the coating method, the film forming method, and the film forming conditions are not limited, and may be set to other materials and 2 degrees, or may be set to other film formation.

In the above embodiment, 'there are R, G, and B colors. In the present invention, in addition to the above, a white pixel that emits light without passing through the filter layer may be provided. Further, in the above-described embodiment, the organic structure [the structure of the light-emitting element has been described, but it is not necessary to include all the layers such as the hole injection film layer 13A and the protective film 15", and other layers may be further provided. . For example, the first electrode 12 may be formed in a two-layer structure in which a transparent conductive film is laminated on a dielectric multilayer film or a reflective film such as A1. In this case, the end face on the light-emitting layer side of the reflective film constitutes an end portion of the resonance portion, and the transparent conductive film constitutes a part of the resonance portion. Further, in the above-described embodiment, the case where the second electrode 14 is constituted by the semi-transmissive reflective layer has been described. However, the second electrode 14 may be formed such that a semi-transmissive reflective layer is laminated in this order from the side of the first electrode. The structure made of transparent electrodes. The transparent electrode is used to reduce the resistance of the semi-transmissive reflective layer, which includes 148898.doc-45-201037828 Γτ 〇 (for material transparent to the light generated in the luminescent layer). The material of the electrode is preferably, for example, η _ Tln 0xlde, indium tin oxide) or contains an conjugate and an oxygen compound. The reason for this is that good electrical conductivity can be obtained even when film formation is carried out at room temperature. The thickness of the transparent electrode can be set, for example, to 3 〇 (10) or more and the sac. Further, in this case, a semi-transmissive reflective layer may be formed as a single end portion, and the other end portion may be provided at a position sandwiching the transparent electrode, and the transparent electrode may be a resonator portion. Further, in the case of providing such a common (four) structure, if the protection _ is formed by a material having a refractive index equal to the refractive index of the material constituting the transparent electrode, the δ film 15 can be made a part of the resonance portion. good. Furthermore, the present invention can also be applied to a configuration in which the second electrode 14 is formed of a transparent electrode, and the reflectance of the end surface of the transparent electrode opposite to the organic layer 13 is increased. The end surface of the first electrode 12 on the side of the light-emitting layer 13 is referred to as a second end portion, and the end surface of the transparent electrode opposite to the organic layer is referred to as a second end portion. For example, the reflectance at the interface with the protective film 15 or the adhesive layer 30 may be increased, and the intersection may be the second end portion. Further, the protective film 15 and the adhesive layer 30 may not be provided, and the transparent electrode may be brought into contact with the atmosphere to increase the reflectance of the interface between the transparent electrode and the atmosphere, and the interface may be the second end. [Second Embodiment] Next, a case where light is emitted from the TFT substrate side will be described as a second embodiment. In the above embodiment, the first electrode 12, the organic layer 13, and the second electrode 14 are laminated on the driving substrate 11 in the order of 14389.doc -46 - 201037828, and the light is applied to the substrate.

Further, for example, in the above embodiment, the case where the second electrode 14 is used as the anode with the second electrode as the anode has been described. However, the anode and the cathode may be reversed and the electrode 12 may be used as the cathode. The electrode (4) is an anode. In this case, as the material of the second electrode 14, a simple substance or an alloy such as gold, silver, or copper, which has a high work function, is preferable, but it may be used by providing a film layer 13 for hole injection. other materials. X, also available in the 2nd electrode! In 4, other elements are added to the extent that the optical constant does not substantially differ. Furthermore, you can also be the first!

In this case, the specific color filter of the present invention can be formed by adding a dye having the above specific peak value by a coloring pattern of one color to three colors recognized in advance. Hereinafter, a color filter, a light sheet having a color pattern of a plurality of colors, and a method of manufacturing the same will be described in detail.

Hereinafter, the coloring pattern formation by the photolithography method, which is one of the forms of the present invention, will be described. ~ The coloring photosensitive composition is used in the photolithography method. The coloring photosensitive composition contains a coloring agent, a coloring agent such as (4), a testable resin, a photopolymerizable compound, a photopolymerization initiator, and the like. In addition to the dyes of the present invention described above, various dyes can also be used in the photolithography method. In addition to this, a known pigment may be added, but it is preferred to treat the pigment in advance with (4) various resins. Gp, pigment is usually synthesized after drying, usually dried by various methods, usually dried to remove the aqueous medium, which is supplied as a powder, but water requires a large amount of latent heat of steaming during the drying process and needs to be supplied Larger thermal energy to form a dry powder. Therefore, it is more common for pigments to form agglomerates (secondary particles) in which primary particles are associated with each other. It is not easy to disperse the pigments forming the agglomerates in the fine particles. And ideal. The resin here is exemplified by the following alkali-soluble resin. As the method of the above dispersion treatment, there are a rinsing treatment or a U-dong method using a kneader, an extruder, a ball mill, a twin roll or a three-roll mill. Among them, the rinsing treatment or the kneading method using the double-grain or three-roll mill is more suitable for micronization. The above rinsing treatment is a method in which an aqueous dispersion of a pigment is usually mixed with a resin solution dissolved in a solvent which is not mixed with water, a pigment is extracted from an aqueous medium into an organic medium, and then the pigment is used for the pigment. 143898.doc •48- 201037828 Theory. According to this method, since the pigment is not dried, it is possible to prevent the pigment from agglomerating and to facilitate the dispersion. Further, the above-described kneading by a two-roll or three-roll mill is a method in which a pigment is mixed with a resin or a resin solution to apply a high shearing force (shearing force) while the pigment is The resin is kneaded to apply a resin to the surface of the pigment, whereby the pigment is treated. The pigment particles agglomerated during this process are dispersed from the lower aggregates to the primary particles. Further, it can also be used as a processing pigment obtained by previously treating with an acrylic resin, a vinyl chloride-vinyl acetate resin, a maleic acid resin, an ethyl cellulose resin, a nitrocellulose resin or the like. As the form of the processed pigment, a powder, a paste, a granule or a paste in which the resin and the pigment are uniformly dispersed are preferred. Further, the block formed by the gelation of the resin is not uniform. The pigments used in the same green, red, and blue pixels used in addition to the color filters having the spectrum of the present invention can be arbitrarily selected in consideration of high transmittance and high color reproducibility. In Ben Maoming, it is necessary to use a fine and granulated pigment for better contempt. In the miniaturization of the organic pigment, it is preferred to use a method comprising the step of subjecting the organic pigment to a liquid composition having a high viscosity together with a water-soluble organic solvent and a water-soluble inorganic salt, and grinding.
