Description

201003144 VI. Description of the Invention: [Technical Field of the Invention] The present invention relates to a color filter for an organic EL display element. [Prior Art] As a method of manufacturing a full-color organic EL display element, the following two methods are known. One of the methods of the younger brothers is to divide the organic EL luminescent materials of various colors in red, green, and blue (four) into fine patterns to form various organic EL luminescent layers of the yule color (for example, Zhao: The money includes, for example, photolithography (phGtQmhGgraphy) Zhuofa> Forging 'left, printing, inkjet, etc.. Medicine: 理理=t by: degree is high temperature, or need to be reactive〗 Muscle radiance The material 1 is suitable for the heat-labile lion unstable heart-shaped ^ ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί However, there is a problem that it is impossible to make a == I:::: mask. Therefore, it is impossible to form a large face, : : degree two: two by: into each pixel, and thus exist as a second - / ^ Changed by time

The problem of luminescent material limitations'.兀# The characteristic is the lowest-emission organic EL. In contrast, the organic i-emitting material is subjected to ink Gnk and is applied by printing or inkjet by a slitting method, particularly an inkjet method, by 321154 3 201003144. The printing of the EL light-emitting layer is considered to be effective particularly in the case of a pattern which is easy to be inked into a sharpness. The second method in which the localized molecular organic EL application is used is to emit white light that is incident on the color filter and emits red and green organic light-emitting layers (for example, referring to Japanese (four)) 2〇〇4-227854 !^^^^^ In the reliability ffi+Λ ^ ^ method, since the color filter can make the excellent balance of the crime, the durability and the durability will not change 4 ' The color is produced instead of the pigment, for example, an organic EL display element. Alternatively, it can be replaced by (4), for example, in the method of filtering the color of the fluorescent material f of light or red light; Liquid _ Using these hiring colors, it is possible to manufacture a large-area, high-definition: piece of color ray manufacturing technology, from the [invention] 】 clarity of organic EL display elements. Usually, from the side tail The tendency of the first layer of illumination to have a long-wavelength color illumination factor. 疋About the long-wavelength side overlaps the other Μ pixels, the green pixel of the ^ and the luminescence peak of the blue eigen/organic EM layer It is also difficult to achieve the τν ^ 目 purity of NTSC or EBU. Either the color of the 4th TV rule or the pixel of the organic display element color produced by the second method is set to a suitable color filter. i' must be in view of the various inventions in view of this颞 颞 Η Η Η Η Η Η Η Η Η 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 321 The light transmittance of the green pixel region is 15% or less in the range of 65 〇ηιπ. ^ In addition, the second color filter of the present invention injures the blue pixel region, and the light transmittance of the pixel region In the range of 5 (10) to the coffee maker, the color is below. According to the verification, the color of the EL display element can be called the color of the element, and the range of the green pixel region 500 to 550 ηπ is preferably 50% or more. The peak of the rate is preferably the light transmittance in the peak of the light transmittance. In addition, the range of the blue pixel region 410 to 470 nm is preferably 50% or more. The peak of the light transmittance of the domain is preferably located at Light transmittance in the peak of light transmittance v Nchuan In addition, it is better to use the organic EL display element as the local molecular organic p-chain-site in the ancient octagonal η organic EL display element.

In addition, it is also possible to chlorinate and react with an amine by using the same method as described above by using the method described in the Japanese Patent Application No. 3-7-7; Manufacturing. These & materials can be used alone or in combination of two or more: 丄: This can adjust the color development. In addition, 'the coloring resin contains 1G to 50 weights of the coloring material based on the total solid denier in the colored resin, and in the present embodiment, 'the blue color is selected from the blue organic EL layer MB first. The resin region 4β has an absorption spectrum of light transmittance of 3〇% or less in the range of 5〇〇 to 321154 33 201003144 550nm. Thereby, the blue resin region 4B sufficiently absorbs light in the vicinity of green. When the blue resin region 4B has a portion having a transmittance of more than 3% by weight in the range of 500 to 550 η π, the light absorbing from the blue organic EL layer 82B, particularly the blue south molecular organic EL layer, cannot be sufficiently removed. Green light, therefore, it is difficult to visualize sufficient color purity. It should be noted that the 'blue resin region 4 β has a high transmittance for blue light, particularly a peak of transmittance of 410 to 470 nm, and a peak transmittance of 5 % or more. Further, the green resin region 4G for wavelength selection of the light emitted from the green organic EL layer 82G has an absorption spectrum having a transmittance of 15% or less in the range of 600 to 65 Å. Thereby, light in the vicinity of orange is sufficiently absorbed. When there is a portion having a transmittance of more than 15% in the range of 6 〇〇 to 65 〇 in the green resin region, the luminescent light from the green organic EL layer 82G, particularly the green polymer organic ruthenium layer, cannot be sufficiently removed. Orange light, therefore, it is difficult to visualize sufficient color purity. It is to be noted that the green resin region 4B has a high transmittance for green light, a peak of transmittance of 5 〇〇 to 55 〇 nm, and a transmittance of 50% or more at the peak of transmittance. good. That is, the green resin region 4G and the blue tree moon region: t or 4B' of the color filter c of the present embodiment have a green organic EL^82G and blue which can sufficiently absorb the corresponding organic rainbow element e, respectively. The light absorption spectrum of the trailing light on the long wavelength side of each of the luminescent apertures of the organic layer 82β. Thereby, light of an unnecessary wavelength range can be sufficiently removed from the light emitted from each of the organic layers 82R, 82G, and 82B, whereby the color purity 321154 34 201003144 can be improved. Thereby, the color of the pixel can be made close to the three primary colors of the NTSC standard. In addition, from the viewpoint of preventing reflection of ambient light in the organic EL display element d, the green resin region 4G and the blue resin region are respectively in the wavelength region of the wavelength reversal, that is, for the green resin region 4G. In the wavelength region of 480 Å or less and 620 nffl or more, the blue tree sap region 4B is preferably a wavelength region of 520 nm or more, and preferably has a transmittance of 10% or less. When the transmittance exceeds (10), the reflectance of the color filter becomes 1% or more, which is not preferable. In the red resin region 4R, light having a wavelength longer than the red wavelength is not a problem. Therefore, any known material that can collect light other than red may be used. In addition, the red resin region U can be used to make the (four) crystal-clear red coloring material according to a known method.

The absorption spectrum of the 4R ^ milk of the various color resin regions can be easily adjusted by the blending or changing of the pigment or the dye with respect to the concentration of the resin. The thickness of the colored resin region is not particularly limited, and may be, for example, 0. 5 to 5 /zm (transparent protective film)

4Γ ^月保复膜5疋 coated black matrix 3 and colored resin area 4R :; As the transparent protective film 5, it is possible to use a transparent material matrix 3 or a colored resin region 4R 4 of an organic her tree or a heat engine to float into a G ^ product or the like, or to mix it into water or the like. The ^b*5 brother in the organic EL layer 82 of the EL element e is 'there may be 1 321 154 35 201003144 even if there is no transparent protective film 5'. The transparent protective film 5 is a film of a transparent inorganic material such as an oxide, a nitride, or a oxynitride-based diamond-like carbon (DLC film) such as Shi Xi, Ming, and the like, and/or a polyethylene lysine resin, and C. Transparent resins such as dilute acid resins, methyl acrylates, and fats are used alone or in layers. The thickness is, for example, scoop 1 to 1 〇 # m. For example, HC-501 manufactured by Sumitomo Chemical Co., Ltd. can be used. (Gasket) As shown in Figs. 1 to 3, the cymbal β is formed on the black matrix 3. As a result, as shown in Fig. 3, the light emitted from the organic EL layers 82R, G, and β is not blocked by the crotch sheet 6, but is output to the outside through the colored resin II domains 4R, 4G, and 4'. The height of the spacer 6 can be set to, for example, 3 to 2 〇 " m. The spacer 6 can be easily formed by photolithography using a photosensitive resin or the like. The photosensitive resin is preferably a resin composition which can be subjected to microfabrication and has a structure in which a sufficient adhesion to the underlayer and a photosensitive property of the compressive strength are used. For example, a composition comprising an unsaturated carboxylic acid and/or an unsaturated carboxylic acid oxime anhydride, an unsaturated compound containing a sulphonyloxy group, and a copolymer of an olefinic unsaturated compound other than the above may be mentioned, A polymerizable compound having an ethylenically unsaturated bond, a radiation-sensitive polymerization initiator, and a color former. Incidentally, as shown in Fig. i, the light shielding walls 61 may be provided at the boundary of each of the colored resin regions 4R, 4G, and 4B on the black matrix 3. Thereby, even if the display element is viewed from a high angle of view, the light transmitted through the adjacent colored resin regions 4R, 4G, and 4B is not mixed. Further, when the color filter e is bonded to the organic element 321154 36 201003144 EL element e, if the light shielding wall 61 is disposed on the black matrix 3, it is not opposed to the light-emitting portions of the respective color organic EL layers 82R, 82G, and 82B. Therefore, it is not easy to damage the organic EL layer 82 by the pressing. The light shielding wall i can be made of the same material as the spacer 6. (Organic EL Element) Next, the organic EL element e will be briefly described. The transparent substrate 2 is the same as the transparent substrate 1. As the colored organic EL layers 82R, 82G, and 82B, a known organic EL material: a bucket can be used. It is especially good to use polymer rainbow materials. Specific examples thereof include a polymer light-emitting material of the type l_ti〇n (manufactured by S u m a t i 〇 n Co., Ltd.). The pixel electrode 9 is, for example, a thin film of metal or the like. The TFT 10 can utilize a well-known substance. The transparent protective film 8 can be made of the same material as the transparent protective film 5. In addition, the resin to be filled between the organic EL element e and the color filter c may be a transparent material, and there is no special purpose, and examples thereof include a photocurable resin such as a acrylate or a resin. (Manufacturing method) For the color filter and the organic EL display device, we will promote the method of manufacturing, and nD a", and we will implement the following methods. (4) (1) Color benefit c and organic EL display element # d. Looking for the exhibition 'Step α): The black matrix forming step is first, in the transparent substrate 1 or the metal light-shielding film, using a spin-coating machine such as a light-shielding resin, and then, by means of; A 321154 37 201003144 optical mask that is coated with an opening corresponding to the shape of the anti-array 3, such as a machine or a die coater, irradiates the transparent substrate i coated with the anti-silver agent with light such as ultraviolet rays, and develops it, thereby forming an anti-surname pattern. (resist (4) (4). 'In addition, the liquid is immersed in a liquid having a septic effect on the light-shielding film, and the rot is sighed with a light-shielding film which is protected by an anti-money agent, and then peeled off the anti-charge agent, thereby forming on the transparent substrate 1. Black matrix 3. Step (2): Colored resin region forming step Next, 'on the transparent substrate i on which the black matrix 3 is formed, a blue transparent coloring agent is applied using a spin coater, a die coater or the like, and Grab to 12 (pre-bake under TC. The light mask of the pattern corresponding to the resin region 4 β is irradiated with light such as ultraviolet rays, and is immersed in the test solution, thereby removing the blue resin region 4 区域 in the region where the light is not irradiated, and sufficiently washing with pure water. Use a box, a heating plate, or the like to heat up to (10) to move C, and repeat the step of the remaining blue resin region 4β ^, that is, the same pattern: the color forms the red domain 4R as 'green' for green The resin region 仏 is patterned to form a stripe-like arrangement of the red, green, and blue colored resin regions 4R, 4G, and 4B periodically. This is the case where the adjacent colored resin regions 4G and sin can be The photosensitive resin material is superimposed on the boundary of 4R and 4R and 4G to form the spacer 6. In the step of forming the colored resin region, in addition to the photolithography method, plating or printing may be used. The colored resin region 4R can be formed by an inkjet method or a printing method, and a transparent coloring resist can be used for the singer s. In the printing method, after the black matrix 3 is formed by using a light-shielding photosensitive resin, it corresponds to the colored resin. Area 3 21154 38 201003144 'The ink pattern of the field is heavy, Nieyang e. Domain 4, 40, 43. Special ^|7 brush' can thus form a colored resin area into a black matrix and a color reversal printing command, which can be simultaneously shaped In the case of using the light-shielding photosensitive tree (fourth), in the ink-jet method, the circumference is covered by the light-shielding structure, and the ink is dried and heat-treated to fill the opening, and then the inkjet method is used. Compared with the photolithography method, it can be used to obtain a color filter. (4) The heating stress is small, so that a heat-resistant coloring material can be suitably used. Also, the coloring material contained in any method Φ #丄(4) ▲ Adjusting the coloring resin region to form a coloring resin region in which the absorption spectrum of the coloring resin region and its concentration relative to the resin are both stepwise. Step (3). Transparent protective film forming step Thereafter, a transparent film can be formed on the transparent substrate on which the colored resin is formed by covering the black matrix 3 and the colored resin regions Μ, K. The transparent protective film 5 can be formed by coating a photocurable or enamel-curable transparent resin film with an earth machine or a non-red coater (by light and/or heat). Cured. In the case where the transparent material 5 is a metal oxide, a nitride, an oxynitride or a DLC film, the inorganic material τ ' can be formed by, for example, a sputtering method or a plasma. Step (4): Step of forming a gasket Further, on the transparent substrate 1 on which the transparent protective film 5 is formed, a photocuring/thermosetting resin such as a propionate is applied by a square coater or the like to perform pre-bake baking. The mask having the pattern corresponding to the shape of the spacer 6 is subjected to development by 321154 39 201003144 = use = aqueous solution, thereby removing the non-exposed portion, and then, 4, and 4 are baked. Thereby, the spacer 6 is formed. In addition, a black matrix or a transparent coloring anti-case is laminated to form a spacer. Step (5): Bonding step On the pre-made organic EL element e, a photocurable resin such as an ultraviolet curable resin is used. In addition, the I device c and the organic rainbow-coated color coated with the photocurable resin are bonded together by a bonding apparatus. The position is adjusted (angnment). (6): At the end of the bonding step, 'the light is applied to the photocurable resin of the organic EL element e and the color filter^ and the 丨 丨 〒 〒 〒 和 和 和 和 和 其 其 其 其 其 其 其 其 其6 Bonding and fixing, complete the organic EL display element d. (Action) The light system emitted from the organic layer of the workpiece 6 of the filter and color filter c of the present embodiment is incident on the 遽.. Γ ±C person is incident on the light system of the S, and the color system is black matrix. 3 Shielding and transmission: The color resin regions 4G, 4B' green light and blue light are wavelength-selected. The individual resin regions constitute pixels that emit light of a specific wavelength. In the color filter of the present embodiment, the green, the transmittance of the meniscus region 4G and the transmittance of the blue resin region 4β are set as described above. Therefore, f·green pixel, blue material _ can be purchased as a difficult element e element e white, green organic EL>f 82G spectrum of the light wavelength side of the trailing part, 32U54 40 201003144 has a ship δ2β generated by the pupil The color purity of the light emitted by the light pixels. It is in various ways. For example, each > can be 4G and the age η is in the known mode, and the above-mentioned iT rate/piece °%4β of the green resin region respectively satisfies the rate of incidence of the trailing portion, and the coloring is required. When the resin region satisfies the above-mentioned transparency and the wood, the color purity of at least one of the colored resin regions is increased. Further, in the above-described appreciation method, although the organic EL element e has a color layer 82R, a green organic EL^82G, and a blue ship layer and emits red light, green light, or blue light, it may have white light emitting white light. The organic red element of the organic layer is substituted for the above organic 乩=piece 乂 white organic EL layer emits white light by containing a plurality of organic rainbow materials. 'In the luminescence from each organic material, it is longer than the peak wave. The tailing on the long wavelength side is the same. Therefore, the organic color of the present invention has the same effect of improving color purity even for an organic EL element having a white organic EL layer. Further, in the above-described embodiment, the red coloring resin region is formed as a red resin region 4R, and the green pixel region is formed as a green resin region 4G as a green resin region 4G. The color/1⁄43⁄4 constitutes a blue pixel region as a blue resin region, whereby reflection of unnecessary external light can be suppressed, but the color of the resin constituting each pixel region is not limited as long as the necessary wavelength absorption characteristics are satisfied. Example 321154 41 201003144 (Production of Organic EL Element) After the TFT substrate having the bank frame was formed, a buffer film (PEDT: poly (3, 4)) was formed by a film thickness of lem. Ethyldioxythiophene/polystyrenesulfonic acid (manufactured by Starck V tech, trade name: Baytr〇n PCH8000). In the same manner, the red pixel is filled with red phosphor ink (LUMATION RP-221 (manufactured by Sumation Co., Ltd.)), and the green pixel is filled with green phosphor ink (LUMATION GP-1200 (manufactured by Sumatimi Co., Ltd.)) After filling the blue pixel with blue luminosity oil 1(10)BP-1()5 (manufactured by Sumatl (10) Co., Ltd.), the ridge agent was removed to form a phosphor layer. After the solvent is sufficiently removed in a vacuum, the charge injection layer is filled with an ink jet printer, the solution is secreted, and the high-purity M-Mg film is used as a cathode, and then a nitriding film is formed by CVD: Thus, an organic EL element e was obtained.
