Description

[Technical Field]

[0001] This invention relates to a resin composition containing a colorant. Furthermore, this invention relates to a film, filter, solid-state imaging element, and image display device using the resin composition. [Previous Technology]

[0002] Using a resin composition containing colorant to manufacture filters such as color filters.

[0003] For example, Patent Document 1 describes a method for manufacturing a color filter using a resin composition, wherein the resin composition contains: organic pigment nanoparticles, which are primary particles with a number average particle size of 50 nm or less and a number average particle size to volume average particle size ratio ([volume average particle size] / [number average particle size]) of 1.0 to 2.0; a graft polymer, which contains at least repeating units of organic pigment residues in the main chain; a polymerizable compound; and a photopolymerization initiator.

[0005] In recent years, there has been a strong demand for miniaturization or thinning in solid-state imaging devices. Therefore, in recent years, there has been a desire to make the films containing color materials such as color filters used in solid-state imaging devices thinner. In order to achieve thinning while maintaining the desired spectral performance, it is necessary to increase the color material concentration of the resin composition used for film formation.

[0006] However, when using pigments as colorants, if the pigment concentration in the resin composition is high, the proportion of materials that can be adsorbed onto the resin or other pigments is relatively reduced. Therefore, there is a tendency for pigments to easily aggregate when storing or coating the resin composition, which may result in pigment agglomerates in the film obtained using the resin composition. If such pigment agglomerates are generated in the film, large-particle-size pigments may be present locally, and the particle size deviation of the pigments present in the film may increase, thus easily causing color inhomogeneity. [Summary of the Invention]

Specific examples of organic solvents include polyethylene glycol monomethyl ether, dichloromethane, methyl 3-ethoxypropionate, ethyl 3-ethoxypropionate, ethyl celecoxib acetate, ethyl lactate, diethylene glycol dimethyl ether, butyl acetate, methyl 3-methoxypropionate, 2-heptanone, 2-pentanone, 3-pentanone, 4-heptanone, cyclohexanone, 2-methylcyclohexanone, 3-methylcyclohexanone, 4-methylcyclohexanone, cycloheptanone, cyclooctanone, cyclohexyl acetate, cyclopentanone, ethyl carbitol acetate, butyl carbitol acetate, propylene glycol monomethyl ether, propylene glycol monomethyl ether, etc. Ether acetates, 3-methoxy-N,N-dimethylpropionic acid, 3-butoxy-N,N-dimethylpropionic acid, propylene glycol diacetate, 3-methoxybutanol, methyl ethyl ketone, γ-butyrolactone, cyclobutane, anisole, 1,4-diethoxybutane, diethylene glycol monoethyl ether acetate, diacetate butane-1,3-diyl, dipropylene glycol methyl ether acetate, diacetone alcohol (also known as diacetone alcohol, 4-hydroxy-4-methyl-2-pentanone), 2-methoxypropyl acetate, 2-methoxy-1-propanol, isopropanol, etc. However, sometimes for environmental reasons, it is better to reduce the amount of aromatic hydrocarbons (benzene, toluene, xylene, ethylbenzene, etc.) used as organic solvents (for example, relative to the total amount of organic solvents, it can be set to 50 ppm by mass (parts per million) or less, or 10 ppm by mass or less, or 1 ppm by mass or less).

[0216] In this invention, it is preferable to use an organic solvent with a low metal content. For example, a metal content of 10 ppb (parts per billion) or less in the organic solvent is preferred. Depending on the need, organic solvents at the ppt (parts per trillion) level can be used, such as those supplied by Toyo Gosei Co., Ltd. (Chemical Industry Daily, November 13, 2015).

[0217] Methods for removing impurities such as metals from organic solvents include, for example, distillation (molecular distillation or membrane distillation) or filtration using a filter. The pore size of the filter used in the filtration is preferably 10 μm or less, more preferably 5 μm or less, and further preferably 3 μm or less. The filter material is preferably polytetrafluoroethylene, polyethylene, or nylon.

[0218] Organic solvents may contain isomers (compounds that have the same number of atoms but different structures). Furthermore, an isomer may contain only one type or multiple types.

[0219] It is preferable that the peroxide content in the organic solvent is below 0.8 mmol / L, and it is even better if it is practically free of peroxides.

[0220] The solvent content in the resin composition is preferably 10-95% by mass, more preferably 20-90% by mass, and even more preferably 30-90% by mass.

[0221] Furthermore, from an environmental control perspective, it is preferable that the resin composition of the present invention is substantially free of environmentally regulated substances.

Examples of environmentally regulated substances include benzene; alkylbenzenes such as toluene and xylene; and halogenated benzenes such as chlorobenzene. These are registered as environmentally regulated substances under REACH (Registration Evaluation Authorization and Restriction of CHemicals), PRTR (Pollutant Release and Transfer Register), and VOC (Volatile Organic Compounds) regulations, and their usage and processing methods are strictly controlled. These compounds are sometimes used as solvents in the manufacture of various components used in the resin composition, and sometimes they are mixed into the resin composition as residual solvents. From the viewpoint of human safety and environmental considerations, it is preferable to minimize the amount of these substances. One method for reducing regulated substances is to heat and depressurize the system to a temperature above the boiling point of the regulated substance, and then distill it off from the system to reduce its concentration. Furthermore, in cases where only small amounts of regulated substances are distilled off, azeotropic distillation with a solvent having the same boiling point as the original solvent is useful to improve efficiency. Additionally, in cases involving compounds with free radical polymerization potential, depressurized distillation can be performed after adding a polymerization inhibitor to suppress free radical polymerization reactions during depressurized distillation, which could lead to intermolecular cross-linking. These distillation removal methods can be performed at any stage, including the raw material stage, the product stage (e.g., polymerized resin solutions and multifunctional monomer solutions), or the stage of preparing a resin composition by mixing these compounds.

[0222] <<Thermosetting Agent>> The resin composition of the present invention can contain a thermosetting agent as a component other than the resin and polymerizable compound described above. Examples of thermosetting agents include compounds having a cyclic ether group. Examples of cyclic ether groups include epoxy groups, oxocyclobutyl groups, etc. The epoxy group can be an alicyclic epoxy group. Furthermore, an alicyclic epoxy group refers to a monovalent functional group having a cyclic structure formed by the condensation of an epoxy ring and a saturated hydrocarbon ring. It is preferable that the compound having a cyclic ether group is a compound having an epoxy group (hereinafter also referred to as an epoxy compound). Examples of epoxy compounds include compounds having one or more epoxy groups per molecule, and compounds having two or more epoxy groups are preferred. It is preferable that the epoxy compound has 1 to 100 epoxy groups per molecule. The upper limit of the number of epoxy groups contained in the epoxy compound can be, for example, 10 or less, or 5 or less. It is preferable that the lower limit of the number of epoxy groups contained in the epoxy compound is two or more. As epoxy compounds, compounds described in Japanese Patent Application Publication No. 2013-011869 (paragraphs 0034-0036), Japanese Patent Application Publication No. 2014-043556 (paragraphs 0147-0156), Japanese Patent Application Publication No. 2014-089408 (paragraphs 0085-0092), and Japanese Patent Application Publication No. 2017-179172 can also be used.

An upper limit of, for example, 15% by mass or less is more preferred, and 10% by mass or less is further preferred. Only one type of thermosetting agent may be used, or two or more types may be used. When two or more types are used, it is preferable that the total content is within the above-mentioned range.

Furthermore, regarding the molecular weight of the polyalkylimide, if the molecular weight can be calculated from the structural formula, the molecular weight of the polyalkylimide is the value calculated from the structural formula. On the other hand, if the molecular weight of a specific amine compound cannot be calculated from the structural formula or is difficult to calculate, the number average molecular weight measured by the boiling point rise method is used. Also, if the boiling point rise method cannot be used or is difficult to measure, the number average molecular weight measured by the viscosity method is used.

Furthermore, for the purposes of preventing metal from leaching from the inner wall of the container, improving the long-term stability of the resin composition, or inhibiting component deterioration, it is preferable to make the inner wall of the container out of glass or stainless steel.

[0258] <Preparation Method of Resin Composition> The resin composition of the present invention can be prepared by mixing the aforementioned components. When preparing the resin composition, all components can be dissolved and / or dispersed in a solvent simultaneously to prepare the resin composition, or, as needed, each component can be appropriately prepared as two or more solutions or dispersions, and then mixed together during use (coating) to prepare the resin composition.

[0259] Furthermore, when preparing the resin composition, it is preferable to include a step of dispersing the pigment. Examples of mechanical forces used for pigment dispersion in this step include compression, extrusion, impact, shearing, and cavitation.

As long as the pore size of the filter is within the above range, fine impurities can be removed more reliably. For the pore size value of the filter, please refer to the nominal value provided by the filter manufacturer. Various filters supplied by NIHON PALL Corporation (DFA4201NXEY, DFA4201NAEY, DFA4201J006P, etc.), Advantec Toyo Kaisha, Ltd., Nihon Entegris KK (Formerly Nippon Mykrolis Corporation), and KITZ MICROFILTER Corporation can be used.

[0263] When using filters, different filters can be combined (e.g., a first filter and a second filter, etc.). In this case, filtration using each filter can be performed only once, or more than twice. Furthermore, filters with different pore sizes can be combined within the aforementioned range. Also, filtration can be performed using the first filter only on the dispersion, and then the second filter can be used for filtration after mixing other components. Furthermore, filters can be appropriately selected based on the hydrophilicity or hydrophobicity of the components.

[0264] <Membrane> The membrane of the present invention is a membrane obtained from the resin composition of the present invention described above. The membrane of the present invention can be used in filters such as color filters, near-infrared transmission filters, and near-infrared cutoff filters.

[0265] The thickness of the membrane of the present invention can be appropriately adjusted according to the purpose. For example, a membrane thickness of 20 μm or less is preferred, 10 μm or less is more preferred, and 5 μm or less is even more preferred. A lower limit of 0.1 μm or more is preferred, 0.2 μm or more is more preferred, and 0.3 μm or more is even more preferred.

[0266] When the film of the present invention is used as a color filter, it is preferable that the film of the present invention has a green, red, blue, cyan, magenta, or yellow hue, more preferably a green, blue, or cyan hue, and even more preferably a green hue. Furthermore, the film of the present invention can be preferably used as a colored pixel in a color filter. Examples of colored pixels include red pixels, green pixels, blue pixels, magenta pixels, cyan pixels, and yellow pixels, with green pixels, blue pixels, or cyan pixels being preferred, and green pixels being even more preferred.

[0267] <Method for Manufacturing the Membrane> Next, a method for manufacturing the membrane of the present invention will be described. The membrane of the present invention can be manufactured by coating the resin composition of the present invention. The method for manufacturing the membrane preferably further includes a step of forming a pattern (pixel). Examples of methods for forming the pattern (pixel) include photolithography and dry etching, with photolithography being preferred.

[0268] The pattern formation based on photolithography preferably includes the following steps: forming a resin composition layer on a support using the resin composition of the present invention; exposing the resin composition layer to form a pattern; and developing and removing the unexposed portion of the resin composition layer to form a pattern (pixel). Depending on the need, a step of baking the resin composition layer (pre-baking step) and a step of baking the developed pattern (pixel) may also be provided (post-baking step).

[0269] In the step of forming the resin composition layer of the present invention, a resin composition layer is formed on a support using a resin composition. There are no particular limitations on the support, and it can be appropriately selected according to the application. For example, glass substrates, silicon substrates, etc., are possible, with silicon substrates being preferred. Furthermore, charge-coupled devices (CCDs), complementary metal-oxide-semiconductor (CMOS) films, transparent conductive films, etc., can be formed on a silicon substrate. Also, sometimes a black matrix is ​​formed on a silicon substrate to isolate each pixel. Furthermore, in order to improve adhesion to the upper layer, prevent material diffusion, or planarize the substrate surface, a base layer can be provided on the silicon substrate. The base layer can also be formed using a composition from the resin composition described in this specification without the colorant, or a composition containing the resin, polymeric compound, surfactant, etc., described in this specification. When measured with diiodomethane, a surface contact angle of 20 to 70° is preferred for the base layer. When measured with water, 30 to 80° is preferred.

[0270] Known methods can be used as coating methods for resin compositions. Examples include drop casting; slot coating; spraying; roller coating; spin coating; cast coating; slot spin coating; pre-wetting (e.g., the method described in Japanese Patent Application Publication No. 2009-145395); inkjet printing (e.g., on-demand, piezoelectric, thermal), nozzle jetting and other ejection systems; flexographic printing; screen printing; gravure printing; reverse offset printing; metal mask printing and other similar printing methods; transfer printing using molds; nanoimprinting, etc. There are no particular limitations on the application methods in inkjet printing. For example, the methods described in "Inkjet Printing That Can Be Promoted and Used - Infinite Possibilities Appearing in Patents - Published February 2005, Sumitbe Techon Research Co., Ltd." (especially pages 115 to 133) or those described in Japanese Patent Application Publication Nos. 2003-262716, 2003-185831, 2003-261827, 2012-126830, and 2006-169325 can be cited. Furthermore, regarding the coating methods for resin compositions, please refer to International Publication Nos. 2017 / 030174 and 2017 / 018419, the contents of which are incorporated herein by reference.

[0271] The resin composition layer formed on the support can be dried (pre-baked). When the film is manufactured using a low-temperature process, pre-baking is not required. When pre-baking is performed, a pre-baking temperature of 150°C or below is preferred, 120°C or below is more preferred, and 110°C or below is even more preferred. The lower limit can be set to 50°C or above, or 80°C or above. A pre-baking time of 10 to 300 seconds is preferred, 40 to 250 seconds is more preferred, and 80 to 220 seconds is even more preferred. Pre-baking can be performed using a heating plate, oven, or the like.

[0272] Next, the resin composition layer is exposed to form a pattern (exposure step). For example, using a stepper or scanning exposure machine, the resin composition layer is exposed through a mask with a predetermined mask pattern, thereby exposing it to form a pattern. This allows the exposed portion to harden.

[0273] Examples of radiation (light) that can be used during exposure include gamma rays and i-rays. Light with wavelengths below 300 nm can also be used (preferably light with wavelengths of 180–300 nm). Examples of light with wavelengths below 300 nm include KrF rays (wavelength 248 nm) and ArF rays (wavelength 193 nm), with KrF rays (wavelength 248 nm) being preferred. Furthermore, light sources with wavelengths above 300 nm can also be used.

[0274] Furthermore, during exposure, exposure can be performed by continuous illumination of light or by pulsed illumination (pulse exposure). Moreover, pulse exposure refers to an exposure method in which light is repeatedly irradiated and paused in a short period of time (e.g., less than milliseconds).

[0275] The irradiation dose (exposure dose) is preferably 0.03 to 2.5 J / cm², and more preferably 0.05 to 1.0 J / cm². Regarding the oxygen concentration during exposure, it can be appropriately selected. Besides exposure under atmospheric conditions, exposure can be performed in a low-oxygen environment with an oxygen concentration of less than 19 vol% (e.g., 15 vol%, 5 vol%, or virtually oxygen-free), or in a high-oxygen environment with an oxygen concentration exceeding 21 vol% (e.g., 22 vol%, 30 vol%, or 50 vol%). Furthermore, the exposure illuminance can be appropriately set, typically within a range of 1000 W / m² to 100000 W / m² (e.g., 5000 W / m², 15000 W / m², or 35000 W / m²). Oxygen concentration and exposure illuminance can be appropriately combined, for example, it can be set to an oxygen concentration of 10% by volume and an illuminance of 10,000 W / m2, an oxygen concentration of 35% by volume and an illuminance of 20,000 W / m2, etc.

[0276] Next, development removes the unexposed portions of the resin composition layer to form a pattern (pixel). The removal of the unexposed portions of the resin composition layer can be performed using a developing solution. Here, the unexposed portions of the resin composition layer from the exposure step dissolve in the developing solution, leaving only the photocured portion. The temperature of the developing solution is preferably, for example, 20–30°C. The development time is preferably 20–180 seconds. Furthermore, to improve residue removal, the step of repeatedly discarding the developing solution every 60 seconds and then supplying new developing solution can be repeated several times.

[0277] Developers can include organic solvents and alkaline developers, with alkaline developers being preferred. As an alkaline developer, an alkaline aqueous solution (alkaline developer) obtained by diluting an alkaline agent with pure water is preferred. Examples of alkaline agents include, for example, organic alkaline compounds such as ammonia, ethylamine, diethylamine, dimethylethanolamine, diglycolamine, hydroxylamine, ethylenediamine, tetramethylammonium hydroxide, tetraethylammonium hydroxide, tetrapropylammonium hydroxide, tetrabutylammonium hydroxide, ethyltrimethylammonium hydroxide, benzyltrimethylammonium hydroxide, dimethylbis(2-hydroxyethyl)ammonium hydroxide, choline, pyrrole, piperidine, and 1,8-diazabicyclo-[5.4.0]-7-undecene, or inorganic alkaline compounds such as sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, sodium silicate, and sodium metasilicate. From an environmental and safety perspective, alkaline agents with large molecular weights are preferred. The concentration of the alkaline agent in the alkaline aqueous solution is preferably 0.001–10% by mass, and more preferably 0.01–1% by mass. Furthermore, the developer may further contain surfactants. From the viewpoint of convenient transportation or storage, the developer can be temporarily prepared as a concentrate and diluted to the required concentration before use. The dilution ratio is not particularly limited, and can be set in the range of 1.5–100 times. It is also preferable to rinse (wash) with pure water after development. It is also preferable to rinse by rotating the support on which the developed resin composition layer has been formed and supplying rinsing solution to the developed resin composition layer. It is also preferable to perform rinsing by moving the nozzle dispensing the rinsing solution from the center of the support to the periphery of the support. In this case, when moving the nozzle from the center of the support to the periphery, the moving speed of the nozzle can be gradually reduced. By rinsing in this manner, in-plane deviation during rinsing can be suppressed. Alternatively, the same effect can be achieved by gradually reducing the rotational speed of the support while moving the nozzle from the center to the periphery of the support.

[0278] After development, it is preferable to perform additional exposure and heating treatment (post-baking) after drying. The additional exposure and post-baking are post-development curing treatments used to produce fully cured films. The heating temperature during post-baking is preferably 100–240°C, and more preferably 200–240°C. The developed film can be post-baked continuously or intermittently using a heating mechanism such as a heating plate, a convection oven (hot air circulating dryer), or a high-frequency heater, in a manner that meets the above conditions. When performing additional exposure, it is preferable to use light with a wavelength of 400 nm or less for exposure. Furthermore, the additional exposure treatment can be performed by the method described in Korean Patent Publication No. 10-2017-0122130.

[0279] Pattern formation based on dry etching preferably includes the following steps: forming a resin composition layer on a support using the resin composition of the present invention, and hardening the entire resin composition layer to form a hardened layer; forming a photoresist layer on the hardened layer; exposing the photoresist layer to a pattern and then developing it to form a photoresist pattern; and using the photoresist pattern as a mask and dry etching the hardened layer using an etching gas. It is preferable to further perform a pre-baking process when forming the photoresist layer. In particular, it is preferable to perform a post-exposure heating treatment and a post-development heating treatment (post-baking treatment) as the photoresist layer formation step. For details on pattern formation using dry etching, please refer to paragraphs 0010 to 0067 of Japanese Patent Application Publication No. 2013-064993, which is incorporated herein by reference.

[0280] <Filter> The filter of the present invention has the film of the present invention as described above. Examples of filters include color filters, near-infrared cut-off filters, and near-infrared transmittance filters, with color filters being preferred. It is preferable that the color filter has the film of the present invention as its pixel, even more preferable that it has the film of the present invention as a colored pixel, and even more preferable that it has the film of the present invention as a green pixel.

[0281] A protective layer can be provided on the surface of the membrane of the present invention for the filter. By providing a protective layer, various functions such as oxidation resistance, low reflectivity, hydrophilicity / hydrophobicity, and shielding of light of a predetermined wavelength (ultraviolet, near-infrared, etc.) can be imparted. The thickness of the protective layer is preferably 0.01 to 10 μm, and more preferably 0.1 to 5 μm. Examples of methods for forming the protective layer include methods of forming by coating a resin composition for forming a protective layer, chemical vapor deposition, and methods of attaching the formed resin with an adhesive material. Examples of components constituting the protective layer include (meth)acrylic resin, olefin-thiol resin, polycarbonate resin, polyether resin, polyaryl ester resin, polyurethane resin, polyetherurethane resin, polystyrene resin, polyaryl ether phosphine oxide resin, polyimide resin, polyamide-amide resin, polyolefin resin, cyclic olefin resin, polyester resin, styrene resin, polyol resin, polyvinylidene chloride resin, melamine resin, polyurethane resin, aromatic polyamide resin, polyamide resin, alkyd resin, epoxy resin, modified polysiloxane resin, fluororesin, polycarbonate resin, polyacrylonitrile resin, cellulose resin, Si, C, W, Al2O3, Mo, SiO2, Si2N4, etc., and may contain two or more of these components. For example, in the case of a protective layer used for oxidation inhibition, it is preferable that the protective layer contains polyol resin, SiO2, and Si2N4. Furthermore, in the case of a protective layer used for low reflectivity, it is preferable that the protective layer contains (meth)acrylic resin and fluoropolymer resin.

[0282] When a protective layer is formed by coating a resin composition, known methods such as spin coating, casting, screen printing, and inkjet printing can be used as the coating method for the resin composition. Known organic solvents (e.g., propylene glycol 1-monomethyl ether 2-acetate, cyclopentanone, ethyl lactate, etc.) can be used as the organic solvent contained in the resin composition. When a protective layer is formed by chemical vapor deposition, known chemical vapor deposition methods (thermochemical vapor deposition, plasma chemical vapor deposition, photochemical vapor deposition) can be used as the chemical vapor deposition method.

[0283] Depending on the requirements, the protective layer may also contain additives such as organic and inorganic microparticles, absorbers of light of a specific wavelength (e.g., ultraviolet, near-infrared, etc.), refractive index modifiers, antioxidants, adhesives, and surfactants. Examples of organic and inorganic microparticles include, for instance, polymeric microparticles (e.g., polysiloxane microparticles, polystyrene microparticles, melamine resin microparticles), titanium dioxide, zinc oxide, zirconium oxide, indium oxide, aluminum oxide, titanium nitride, titanium oxynitride, magnesium fluoride, hollow silica, silica, calcium carbonate, and barium sulfate. Known absorbers can be used as absorbers of the specific wavelength of light. The content of these additives can be appropriately adjusted, but 0.1 to 70% by mass relative to the total mass of the protective layer is preferred, and 1 to 60% by mass is further preferred.

[0284] Furthermore, as a protective layer, the protective layer described in paragraphs 0073 to 0092 of Japanese Patent Application Publication No. 2017-151176 may also be used.

[0285] The filter may also have the following structure: each pixel is embedded in a space separated by partitions, for example, in a grid pattern.

[0286] <Solid-State Imaging Element> The solid-state imaging element of the present invention has the film of the present invention described above. As for the structure of the solid-state imaging element, there are no particular limitations as long as it has the film of the present invention and functions as a solid-state imaging element; for example, the following structures can be cited.

[0287] The structure of the imaging element is as follows: A transmission electrode, composed of a plurality of photodiodes constituting the light-receiving area of ​​a solid-state imaging element (CCD (charge-coupled device) image sensor, CMOS (complementary metal oxide semiconductor) image sensor, etc.), is provided on a substrate. A light-shielding film, with openings only in the light-receiving portion of the photodiodes, is provided on the photodiodes and the transmission electrode. An element protective film, composed of silicon nitride or the like, is formed on the light-shielding film to cover the entire surface of the film and the light-receiving portion of the photodiodes. A color filter is provided on the element protective film. Furthermore, the structure may have a light-gathering mechanism (e.g., a microlens, etc. The same applies hereinafter) on the device protective film and on the underside (near the substrate) of the color filter, or a structure with a light-gathering mechanism on the color filter. The color filter may also have a structure in which each colored pixel is embedded in a space separated by partitions, for example, in a grid pattern. In this case, it is preferable that the refractive index of the partitions is lower than that of each colored pixel. Examples of camera devices with this structure include those described in Japanese Patent Application Publication No. 2012-227478, Japanese Patent Application Publication No. 2014-179577, and International Publication No. 2018 / 043654. Furthermore, as shown in Japanese Patent Application Publication No. 2019-211559, providing an ultraviolet absorption layer within the structure of the solid-state camera element can also improve lightfastness. Camera devices equipped with the solid-state camera element of the present invention can be used not only as digital cameras or electronic devices with camera functions (such as mobile phones), but also as vehicle-mounted cameras or surveillance cameras.

[0288] <Image Display Device> The image display device of the present invention has the film of the present invention described above. Examples of image display devices include liquid crystal display devices and organic electroluminescent display devices.

Furthermore, liquid crystal display devices are described, for example, in "Next-Generation Liquid Crystal Display Technology" (edited by Tatsuo Uchida, published by Kogyo Chosakai Publishing Co., Ltd., 1994). There are no particular limitations on the liquid crystal display devices to which the present invention can be applied; for example, liquid crystal display devices of various types described in the aforementioned "Next-Generation Liquid Crystal Display Technology" can be applied.

[0298] <Preparation of Pigment Dispersions> Using a bead mill (using zirconia beads with a diameter of 0.1 mm), the mixture of materials listed in the table below was mixed and dispersed for 3 hours. Then, it was dispersed using a NANO-3000-10 high-pressure disperser with a pressure reduction mechanism (manufactured by Nippon BEE Co., Ltd.) at a pressure of 2000 MPa and a flow rate of 500 g / min. This dispersion process was repeated 10 times to obtain various pigment dispersions. The values ​​listed in the table below are parts by mass. The average particle size (nm) and viscosity (mPa・s) of the pigment in each pigment dispersion are also recorded. The average particle size of the pigment was measured using a nanoSAQLA (manufactured by Otsuka Electronics Co., Ltd.) by dynamic light scattering. The viscosity of the pigment dispersion was measured by adjusting the temperature of the pigment dispersion to 25°C.

[0314] <Performance Evaluation> (Color Inhomogeneity) A substrate forming composition (CT-4000, manufactured by FUJIFILM Electronic Materials Co.,LTD.) was coated onto a glass substrate using spin coating to achieve a film thickness of 0.1 μm. The substrate was then heated at 220°C for 1 hour using a hot plate to form the substrate. Each resin composition was then coated onto the glass substrate with the substrate attached using spin coating, followed by heating at 100°C for 2 minutes using a hot plate to obtain a composition layer with a film thickness of 0.5 μm. The composition layer was exposed to 365 nm light using an I-ray stepper exposure apparatus FPA-3000i5+ (manufactured by Canon Inc.) at an exposure dose of 500 mJ / cm². The exposed composition layer was then subjected to a 60-second spin-immersion development using a 0.3% (w / w) aqueous solution of tetramethylammonium hydroxide at 23°C. Finally, it was rinsed with water by a rotating spray and then washed with pure water. Then, water droplets were blown away with high-pressure air, and the glass substrate was allowed to dry naturally. It was then baked at 220°C for 300 seconds using a heating plate to form a film. Using the glass substrate with this film (evaluation substrate), the brightness distribution was analyzed using the following method, and color non-uniformity was evaluated based on the number of pixels whose deviation from the average was ±10% or more. The method for measuring the brightness distribution is explained. The evaluation substrate was placed between the observation lens and the light source of an optical microscope and illuminated towards the observation lens. Its light transmission state was observed using an MX-50 optical microscope (manufactured by Olympus Corporation) equipped with a digital camera. The film surface was photographed in five randomly selected areas. The brightness of the photographed images was quantified and saved using a density distribution of 256 tones from 0 to 255. The brightness distribution was analyzed from the images, and color non-uniformity was evaluated based on the number of pixels whose deviation from the average exceeded ±10%. The evaluation criteria are as follows. If the evaluation is A to C, it is considered to be practically sound. A: The number of pixels with a deviation from the average exceeding ±10% is less than 1000. B: The number of pixels with a deviation from the average exceeding ±10% is more than 1000 but less than 3000. C: The number of pixels with a deviation from the average exceeding ±10% is more than 3000 but less than 5000. D: The number of pixels with a deviation from the average exceeding ±10% is more than 5000.

[0315] (Coarse Particles) A ​​substrate forming composition (CT-4000, manufactured by FUJIFILM Electronic Materials Co., Ltd.) was coated onto a glass substrate using a spin coater to achieve a thickness of 0.1 μm after baking. The substrate was then formed by heating at 220°C for 300 seconds using a hot plate, thus obtaining a glass substrate (support) with a substrate layer attached. Various resin compositions were then coated onto the glass substrate with the substrate layer attached using a spin coater, followed by heating at 100°C for 2 minutes using a hot plate, thereby forming a layer with a film thickness of 0.5 μm. Foreign matter in the film was detected using a Conplus III foreign matter evaluation device (manufactured by Applied Materials, Inc.). The number of foreign matter (coarse particles) with a maximum width of 1.0 μm or more was visually observed and the number of coarse particles with a maximum width of 1.0 μm or more (number of coarse particles per 1 cm²) was calculated. A: The number of coarse particles per 1 cm² of membrane is less than 10. B: The number of coarse particles per 1 cm² of membrane is more than 10 but less than 30. C: The number of coarse particles per 1 cm² of membrane is more than 30 but less than 100. D: The number of coarse particles per 1 cm² of membrane is more than 100.

[0316] (Developability) A substrate forming composition (CT-4000, manufactured by FUJIFILM Electronic Materials Co., Ltd.) was coated onto an 8-inch (20.32 cm) silicon wafer using a spin coater to achieve a post-baking thickness of 0.1 μm. The substrate was then formed by heating at 220°C for 300 seconds using a hot plate, resulting in a silicon wafer (support) with a substrate. Next, each resin composition was coated using spin coating to achieve a post-baking film thickness of 0.62 μm. Then, the wafer was heated at 100°C for 2 minutes using a hot plate. Finally, light at a wavelength of 365 nm was exposed using an I-ray stepper exposure unit FPA-3000i5+ (manufactured by Canon Inc.) with an exposure dose of 1000 mJ / cm² through a 1.0 μm square dot pattern mask. Next, the silicon wafer with the exposed coating film was placed on the horizontal turntable of a rotary spray developer (DW-30 type, manufactured by CHEMITRONICS CO.,Ltd.). After 60 seconds of immersion development at 23°C using a 60% diluted CD-2000 solution (manufactured by FUJIFILM Electronic Materials Co.,Ltd.), the silicon wafer was fixed to the turntable using a vacuum chuck. While the silicon wafer was rotated at 50 rpm, pure water was sprayed from above its center of rotation through a nozzle for rinsing. Afterward, it was spray-dried. Furthermore, it was heated for 300 seconds at 200°C (post-baking) to form a pattern (pixels). The silicon wafer with the formed pixels was observed using a scanning electron microscope (SEM) (10000x magnification), and its developability was evaluated according to the following criteria. A: No residue is detected outside the pixel formation area (unexposed area). B: Very little residue is detected outside the pixel formation area (unexposed area), to the point of being practically harmless. C: Slight residue is detected outside the pixel formation area (unexposed area), to the point of being practically harmless. D: Significant residue is detected outside the pixel formation area (unexposed area).

[0317] (Stability over Time) The viscosity (mPa·s) of the resin compositions of the Examples and Comparative Examples was measured using a "RE-85L" manufactured by TOKI SANGYO CO.,LTD. After the above measurements, the resin compositions were allowed to stand at 45°C, in the dark, for 5 days, and the viscosity (mPa·s) was measured again. The stability over time was evaluated based on the viscosity difference (ΔVis) before and after the above standing conditions according to the following evaluation criteria. It can be said that the smaller the value of the viscosity difference (ΔVis), the better the stability of the resin composition over time. All the above viscosity measurements were performed in a laboratory with the temperature and humidity controlled at 22±5°C and 60±20%, respectively, and the temperature of the resin composition was adjusted to 25°C. All measurements were performed three times, and the average value was used. A: Δvis is less than 0.2 mPa·s B: Δvis exceeds 0.2 mPa·s but is less than 0.3 mPa·s C: Δvis exceeds 0.3 mPa·s but is less than 0.5 mPa·s D: Δvis exceeds 0.5 mPa·s [Table 21] formula Pigment dispersion
