Description

[Technical Field]

[0001] The present invention relates to a coloring composition containing a colorant. The present invention also relates to a film, a color filter, and a solid-state imaging device using the coloring composition. [Background technology]

[0002] In recent years, the demand for solid-state imaging devices such as charge-coupled device (CCD) image sensors has grown significantly due to the widespread use of digital cameras and camera-equipped mobile phones. Color filters are used as key devices in displays and optical elements.

[0003] Patent Document 1 describes a cyan coloring composition for color filters, which contains a phthalocyanine blue pigment containing either or both of Color Index Pigment Blue 15:3 and Color Index Pigment Blue 15:4, a phthalocyanine green pigment containing Color Index Pigment Green 7, a resin, a polymerizable compound, and a photopolymerization initiator.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-052239 Summary of the Invention [Problem to be solved by the invention]

[0005] When pixels are formed by a photolithography method using a coloring composition containing a colorant, a polymerizable compound, and a photopolymerization initiator, the coloring composition is applied to a support to form a composition layer, which is then exposed to light through a mask having a pattern, and the unexposed areas are developed and removed to form pixels.

[0006] The present inventors have conducted extensive research into coloring compositions for forming cyan pixels and have found that increasing the illuminance during exposure tends to increase the line width of the resulting pixels. Thus, it has been found that the line width of the resulting pixels is highly dependent on the illuminance of the coloring composition for forming cyan pixels.

[0007] In addition, when forming pixels using a coloring composition, the pixels may be formed using a coloring composition that has been stored at low temperatures for a long period of time. If the sensitivity of the coloring composition decreases during storage, the line width of the resulting pixels is likely to differ even if the pixels are formed under the same exposure conditions as those of the coloring composition before storage. For this reason, it is desirable for the coloring composition to have excellent stability of sensitivity over time.

[0008] The present inventors have furthered their investigation into the colored composition described in Patent Document 1, and have found that the line width of the resulting pixel also depends greatly on the illuminance.

[0009] Therefore, an object of the present invention is to provide a coloring composition which exhibits small dependency of the line width of the obtained pixel on illuminance and excellent stability of sensitivity over time. Another object of the present invention is to provide a film, a color filter, and a solid-state imaging device. [Means for solving the problem]

Specific examples of organic solvents include polyethylene glycol monomethyl ether, dichloromethane, methyl 3-ethoxypropionate, ethyl 3-ethoxypropionate, ethyl cellosolve 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 ...

[0184] In the present invention, it is preferable to use an organic solvent with a low metal content. The metal content of the organic solvent is preferably, for example, 10 mass ppb (parts per billion) or less. If necessary, organic solvents with mass ppt (parts per trillion) levels may be used, and such organic solvents are provided, for example, by Toyo Gosei Co., Ltd. (The Chemical Daily, November 13, 2015).

[0185] Methods for removing impurities such as metals from organic solvents include, for example, distillation (molecular distillation, thin-film distillation, etc.) and filtration using a filter. The pore size of the filter used for filtration is preferably 10 μm or less, more preferably 5 μm or less, and even more preferably 3 μm or less. The filter material is preferably polytetrafluoroethylene, polyethylene, or nylon.

[0186] The organic solvent may contain isomers (compounds with the same number of atoms but different structures), and may contain only one type of isomer or multiple types of isomers.

[0187] The organic solvent preferably has a peroxide content of 0.8 mmol / L or less, and more preferably contains substantially no peroxide.

[0188] The content of the solvent in the coloring composition is preferably from 10 to 95% by mass, more preferably from 20 to 90% by mass, and even more preferably from 30 to 90% by mass.

[0189] In addition, from the viewpoint of environmental regulations, the coloring composition of the present invention preferably does not substantially contain environmentally restricted substances. In the present invention, "substantially free of environmentally restricted substances" means that the content of environmentally restricted substances in the coloring composition is 50 ppm by mass or less, preferably 30 ppm by mass or less, more preferably 10 ppm by mass or less, and particularly preferably 1 ppm by mass or less. Examples of environmentally restricted substances include benzene; alkylbenzenes such as toluene and xylene; and halogenated benzenes such as chlorobenzene. These substances are registered as environmentally restricted substances under the REACH (Registration Evaluation Authorization and Restriction of Chemicals) regulations, the PRTR (Pollutant Release and Transfer Register) Act, and the VOC (Volatile Organic Compounds) regulations, and their usage amounts and handling methods are strictly regulated. These compounds may be used as solvents when producing components used in the coloring composition, and may be mixed into the coloring composition as residual solvents. From the viewpoints of human safety and environmental considerations, it is preferable to reduce the content of these substances as much as possible. Examples of methods for reducing environmentally regulated substances include heating or reducing the pressure in the system to a temperature above the boiling point of the environmentally regulated substance, thereby distilling off the environmentally regulated substance from the system. When distilling off a small amount of an environmentally regulated substance, it is also useful to perform azeotropy with a solvent having a boiling point equivalent to that of the solvent in question in order to increase efficiency. When a radically polymerizable compound is contained, a polymerization inhibitor or the like may be added before distillation under reduced pressure to prevent intermolecular crosslinking due to the progression of a radical polymerization reaction during distillation under reduced pressure. These distillation methods can be used at any stage, such as the stage of raw materials, the stage of a product obtained by reacting the raw materials (for example, a resin solution or a polyfunctional monomer solution after polymerization), or the stage of a colored composition prepared by mixing these compounds.

Furthermore, it is also preferable to make the inner wall of the container out of glass or stainless steel in order to prevent metal elution from the inner wall of the container, improve the storage stability of the coloring composition, and prevent deterioration of the components.

[0227] <Method for preparing coloring composition> The colored composition of the present invention can be prepared by mixing the above-mentioned components. When preparing the colored composition, all components may be simultaneously dissolved and / or dispersed in a solvent to prepare the colored composition, or, if necessary, each component may be prepared as two or more appropriate solutions or dispersions, which may be mixed at the time of use (at the time of application) to prepare the colored composition.

[0228] Furthermore, the preparation of the coloring composition preferably includes a process for dispersing the pigment. In the process for dispersing the pigment, mechanical forces used to disperse the pigment include compression, squeezing, impact, shear, and cavitation. Specific examples of these processes include a bead mill, a sand mill, a roll mill, a ball mill, a paint shaker, a microfluidizer, a high-speed impeller, a sand grinder, a flow jet mixer, high-pressure wet atomization, and ultrasonic dispersion. Furthermore, when grinding the pigment in a sand mill (bead mill), it is preferable to use small-diameter beads, increase the bead packing ratio, or otherwise increase the grinding efficiency under such conditions. Furthermore, it is preferable to remove coarse particles after the grinding process by filtration, centrifugation, or the like. In addition, the process and disperser for dispersing pigments can be suitably described in "Dispersion Technology Encyclopedia," published by Joho Kiko Co., Ltd., July 15, 2005, or "Dispersion Technology and Industrial Applications Focused on Suspension (Solid / Liquid Dispersion Systems) - Comprehensive Data Collection," published by Management Development Center Publishing Department, October 10, 1978, or in paragraph 0022 of JP 2015-157893 A. The process for dispersing pigments can also include a salt milling step to refine the particles. The materials, equipment, and processing conditions used in the salt milling step can be found in, for example, JP 2015-194521 A and JP 2012-046629 A.

[0229] When preparing a coloring composition, it is preferable to filter the coloring composition for the purpose of removing foreign matter and reducing defects. Any filter that has been conventionally used for filtration or the like can be used without any particular limitation. Examples of such filters include filters made of materials such as fluororesins such as polytetrafluoroethylene (PTFE) and polyvinylidene fluoride (PVDF), polyamide resins such as nylon (e.g., nylon-6, nylon-6,6), and polyolefin resins (including high-density and ultra-high-molecular-weight polyolefin resins) such as polyethylene and polypropylene (PP). Among these materials, polypropylene (including high-density polypropylene) and nylon are preferred.

[0230] The pore size of the filter is preferably 0.01 to 7.0 μm, more preferably 0.01 to 3.0 μm, and even more preferably 0.05 to 0.5 μm. If the pore size of the filter is within the above range, fine foreign matter can be removed more reliably. The nominal value of the filter manufacturer can be referred to for the pore size value of the filter. Various filters provided by Nippon Pall Corporation (DFA4201NIEY, DFA4201NAEY, DFA4201J006P, etc.), Advantech Toyo Co., Ltd., Nippon Integris Co., Ltd. (formerly Nippon Microlith Co., Ltd.), Kitz Microfilter Co., Ltd., etc. can be used.

[0231] It is also preferable to use a fibrous filter medium as the filter. Examples of fibrous filter medium include polypropylene fiber, nylon fiber, and glass fiber. Commercially available products include the SBP type series (SBP008, etc.), TPR type series (TPR002, TPR005, etc.), and SHPX type series (SHPX003, etc.) manufactured by ROKI TECHNO CORPORATION.

[0232] When using filters, different filters (for example, a first filter and a second filter) may be combined. In this case, filtration with each filter may be performed only once or twice or more times. Filters with different pore sizes within the above-mentioned range may be combined. Filtration with the first filter may be performed on the dispersion liquid alone, and filtration with the second filter may be performed after mixing with other components. An appropriate filter can be selected depending on the hydrophilicity or hydrophobicity of the composition.

[0233] <Membrane> The film of the present invention is a film obtained from the colored composition of the present invention described above. The film of the present invention can be used for color filters, etc. Specifically, it can be preferably used as a colored layer (pixel) of a color filter, and more preferably as a cyan pixel. The film thickness of the film of the present invention can be appropriately adjusted depending on the purpose, but is preferably 0.1 to 20 μm. The upper limit of the film thickness is preferably 10 μm or less, more preferably 5 μm or less, even more preferably 3 μm or less, and particularly preferably 1.5 μm or less. The lower limit of the film thickness is preferably 0.2 μm or more, more preferably 0.3 μm or more.

[0234] The film of the present invention preferably has an average transmittance of 75% or more, more preferably 80% or more, and even more preferably 85% or more, for light having a wavelength in the range of 400 to 450 nm, and the upper limit can be set to 100% or less. Furthermore, the film of the present invention preferably has an average transmittance of 30% or less, more preferably 25% or less, and even more preferably 20% or less, for light having a wavelength in the range of 650 to 700 nm. The lower limit can be 0% or more. Furthermore, the film of the present invention preferably exhibits a transmittance of 50% at a wavelength of light in the range of 560 to 590 nm, more preferably in the range of 565 to 585 nm, and even more preferably in the range of 570 to 580 nm.

[0235] <Pixel formation method> A method for forming pixels will now be described. By using the colored composition of the present invention, for example, cyan pixels can be formed.

[0236] The method for forming pixels preferably includes a step of applying a coloring composition on a support to form a coloring composition layer, a step of patternwise exposing the coloring composition layer, and a step of developing the coloring composition layer after exposure.

[0237] In the step of forming the coloring composition layer, the coloring composition is applied to a support to form the coloring composition layer. The support is not particularly limited and can be appropriately selected depending on the application. Examples include a glass substrate and a silicon substrate, with a silicon substrate being preferred. The silicon substrate may also be formed with a charge-coupled device (CCD), a complementary metal-oxide semiconductor (CMOS), a transparent conductive film, or the like. A black matrix is ​​sometimes formed on the silicon substrate to isolate each pixel. The silicon substrate may also be provided with an underlayer to improve adhesion to an upper layer, prevent diffusion of substances, or flatten the substrate surface. The underlayer may be formed using a composition obtained by removing the colorant from the coloring composition described herein, or a composition containing the resin, polymerizable compound, surfactant, or the like described herein. The surface contact angle of the underlayer is preferably 20 to 70° when measured with diiodomethane. It is also preferably 30 to 80° when measured with water.

[0238] The coloring composition can be applied by any known method, including, for example, a dropping method (drop casting), a slit coating method, a spray method, a roll coating method, a rotary coating method (spin coating), a casting coating method, a slit and spin method, a pre-wetting method (for example, a method described in JP-A-2009-145395), various printing methods such as inkjet (for example, an on-demand method, a piezo method, a thermal method), ejection printing such as nozzle jet, flexographic printing, screen printing, gravure printing, reverse offset printing, and metal mask printing, a transfer method using a mold, and a nanoimprint method. The inkjet application method is not particularly limited, and examples thereof include the method described in "Expanding and Usable Inkjet - Infinite Possibilities Seen in Patents -", ​​published February 2005 by Sumibe Techno Research (particularly pages 115 to 133), and the methods described in JP 2003-262716 A, JP 2003-185831 A, JP 2003-261827 A, JP 2012-126830 A, JP 2006-169325 A, etc. Furthermore, for the application method of the coloring composition, the descriptions in WO 2017 / 030174 and WO 2017 / 018419 can be referred to, the contents of which are incorporated herein by reference.

[0239] The colored composition layer formed on the support may be dried (prebaked). When a film is produced by a low-temperature process, prebaking may not be performed. When prebaking is performed, the prebaking temperature is preferably 150°C or lower, more preferably 120°C or lower, and even more preferably 110°C or lower. The lower limit can be, for example, 50°C or higher, or can also be 80°C or higher. The prebaking time is preferably 10 to 300 seconds, more preferably 40 to 250 seconds, and even more preferably 80 to 220 seconds. Prebaking can be performed using a hot plate, an oven, or the like.

[0240] Next, the coloring composition layer is exposed to light in a pattern (exposure step). For example, the coloring composition layer can be exposed to light in a pattern by using a stepper exposure machine, a scanner exposure machine, or the like, through a mask having a predetermined mask pattern. This allows the exposed portion to be cured.

[0241] Examples of radiation (light) that can be used for exposure include g-rays and i-rays. Light with a wavelength of 300 nm or less (preferably light with a wavelength of 180 to 300 nm) can also be used. Examples of light with a wavelength of 300 nm or less include KrF rays (wavelength 248 nm) and ArF rays (wavelength 193 nm), with KrF rays (wavelength 248 nm) being preferred. Long-wave light sources with wavelengths of 300 nm or more can also be used.

[0242] Furthermore, the exposure may be performed by continuous irradiation with light or by pulsed irradiation (pulse exposure), which is an exposure method in which light irradiation and pauses are repeated in short cycles (for example, milliseconds or less).

[0243] The irradiation amount (exposure amount) is, for example, 0.03 to 2.5 J / cm 2 is preferable, and 0.05 to 1.0 J / cm 2 The oxygen concentration during exposure can be appropriately selected. In addition to being performed in the atmosphere, exposure may be performed in a low-oxygen atmosphere with an oxygen concentration of 19% by volume or less (e.g., 15% by volume, 5% by volume, or substantially oxygen-free), or in a high-oxygen atmosphere with an oxygen concentration of more than 21% by volume (e.g., 22% by volume, 30% by volume, or 50% by volume). The exposure illuminance can be appropriately set, and is usually 1000 W / m 2 ~100,000W / m 2 (e.g., 5000W / m 2 , 15000W / m 2 , or 35,000 W / m 2 The oxygen concentration and exposure illuminance may be appropriately combined. For example, an oxygen concentration of 10% by volume and an illuminance of 10,000 W / m 2, oxygen concentration 35% by volume, illuminance 20000W / m 2 etc.

[0244] Next, the unexposed portions of the coloring composition layer are developed and removed to form a pattern (pixels). The unexposed portions of the coloring composition layer can be developed and removed using a developer. As a result, the coloring composition layer in the unexposed portions in the exposure step is dissolved into the developer, leaving only the photocured portions. The temperature of the developer is preferably, for example, 20 to 30°C. The development time is preferably 20 to 180 seconds. In addition, to improve residue removal, the process of shaking off the developer every 60 seconds and then supplying fresh developer may be repeated several times.

[0245] Examples of the developer include organic solvents and alkaline developers, with alkaline developers being preferred. The alkaline developer is preferably an alkaline aqueous solution (alkaline developer) prepared by diluting an alkaline agent with pure water. Examples of the alkaline agent include organic alkaline compounds such as ammonia, ethylamine, diethylamine, dimethylethanolamine, diglycolamine, diethanolamine, hydroxyamine, 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, as well as inorganic alkaline compounds such as sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, sodium silicate, and sodium metasilicate. Alkaline agents with high molecular weights are preferred from an environmental and safety perspective. The concentration of the alkaline agent in the alkaline aqueous solution is preferably 0.001 to 10% by mass, more preferably 0.01 to 1% by mass. The developer may further contain a surfactant. For ease of transportation and storage, the developer may be prepared as a concentrated solution and then diluted to the required concentration before use. The dilution ratio is not particularly limited, but can be set, for example, in the range of 1.5 to 100 times. It is also preferable to wash (rinse) the developed layer with pure water after development. Rinsing is preferably performed by supplying a rinse solution to the developed colored composition layer while rotating the support on which the developed colored composition layer has been formed. It is also preferable to perform the rinse by moving the nozzle ejecting the rinse solution from the center of the support to the periphery of the support. In this case, the nozzle movement speed may be gradually reduced as the nozzle moves from the center to the periphery of the support. Rinsing in this manner can suppress in-plane variations in rinsing. A similar effect can be achieved by gradually reducing the rotation speed of the support while moving the nozzle from the center to the periphery of the support.

[0246] After development and drying, it is preferable to perform additional exposure treatment or heating treatment (post-baking). The additional exposure treatment or post-baking is a post-development curing treatment to ensure complete curing. The heating temperature in post-baking is, for example, preferably 100 to 240°C, more preferably 200 to 240°C. Post-baking can be performed continuously or batchwise using a heating means such as a hot plate, convection oven (hot air circulation dryer), or high-frequency heater to heat the developed film to the above conditions. When additional exposure treatment is performed, it is preferable that the light used for exposure has a wavelength of 400 nm or less. The additional exposure treatment may also be performed by the method described in Korean Patent Publication No. 10-2017-0122130.

[0247] <Color filter> The color filter of the present invention has the above-described film of the present invention. Preferably, the film of the present invention is used as a color pixel of the color filter, more preferably as a cyan pixel. The color filter of the present invention can be used in a solid-state imaging device, an image display device, or the like.

[0248] The color filter of the present invention preferably has colored pixels of other hues in addition to the pixels of the film of the present invention. Examples of colored pixels of other hues include blue pixels, red pixels, yellow pixels, and magenta pixels. A preferred embodiment of the color filter of the present invention includes a cyan pixel, a yellow pixel, and a magenta pixel formed from the film of the present invention. The color filter may have a structure in which each colored pixel is embedded in a space partitioned, for example, in a lattice pattern, by partition walls. In this case, the partition walls preferably have a lower refractive index than each colored pixel. Furthermore, the partition walls may be formed in the configuration described in U.S. Patent Application Publication No. 2018 / 0040656.

[0249] The color filter may have a protective layer provided on the surface of the film of the present invention. By providing a protective layer, various functions can be imparted, such as oxygen blocking, low reflectivity, hydrophilicity / hydrophobicity, and blocking of light of specific wavelengths (ultraviolet rays, near-infrared rays, etc.). The thickness of the protective layer is preferably 0.01 to 10 μm, more preferably 0.1 to 5 μm. Methods for forming the protective layer include a method of applying a resin composition dissolved in an organic solvent, a chemical vapor deposition method, and a method of attaching a molded resin with an adhesive. Components constituting the protective layer include (meth)acrylic resins, enethiol resins, polycarbonate resins, polyether resins, polyarylate resins, polysulfone resins, polyethersulfone resins, polyphenylene resins, polyarylene ether phosphine oxide resins, polyimide resins, polyamideimide resins, polyolefin resins, cyclic olefin resins, polyester resins, styrene resins, polyol resins, polyvinylidene chloride resins, melamine resins, urethane resins, aramid resins, polyamide resins, alkyd resins, epoxy resins, modified silicone resins, fluororesins, polycarbonate resins, polyacrylonitrile resins, cellulose resins, Si, C, W, Al2O3, Mo, SiO2, and Si2N4, and may contain two or more of these components. For example, in the case of a protective layer intended to block oxygen, the protective layer preferably contains a polyol resin, SiO2, and Si2N4. Furthermore, in the case of a protective layer intended to reduce reflectivity, the protective layer preferably contains a (meth)acrylic resin and a fluororesin.

[0250] When forming a protective layer by applying a resin composition, known methods such as spin coating, casting, screen printing, and inkjet printing can be used as the method for applying 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 forming the protective layer by chemical vapor deposition, known chemical vapor deposition methods (thermal chemical vapor deposition, plasma chemical vapor deposition, photochemical vapor deposition) can be used as the chemical vapor deposition method.

[0251] The protective layer may contain additives such as organic or inorganic fine particles, absorbers of specific wavelengths of light (e.g., ultraviolet light, near-infrared light, etc.), refractive index modifiers, antioxidants, adhesives, and surfactants, as needed. Examples of organic or inorganic fine particles include polymeric fine particles (e.g., silicone resin fine particles, polystyrene fine particles, melamine resin fine particles), titanium oxide, zinc oxide, zirconium oxide, indium oxide, aluminum oxide, titanium nitride, titanium oxynitride, magnesium fluoride, hollow silica, silica, calcium carbonate, and barium sulfate. Known absorbers of specific wavelengths of light can be used. The content of these additives can be adjusted as needed, but is preferably 0.1 to 70% by mass, and more preferably 1 to 60% by mass, of the total mass of the protective layer.

[0252] Furthermore, as the protective layer, the protective layers described in paragraphs 0073 to 0092 of JP-A No. 2017-151176 can also be used.

[0253] <Solid-state imaging element> The solid-state imaging device of the present invention has the above-described film of the present invention. The configuration of the solid-state imaging device is not particularly limited as long as it has the film of the present invention and functions as a solid-state imaging device, but examples thereof include the following configurations.

[0254] The substrate includes a plurality of photodiodes constituting the light receiving area of ​​a solid-state imaging device (such as a CCD (charge-coupled device) image sensor or a CMOS (complementary metal-oxide semiconductor) image sensor) and transfer electrodes formed of polysilicon or the like. A light-shielding film is formed on the photodiodes and transfer electrodes, with only the light-receiving portions of the photodiodes exposed. A device protection film formed of silicon nitride or the like is formed on the light-shielding film so as to cover the entire light-shielding film and the light-receiving portions of the photodiodes. A color filter is also formed on the device protection film. Furthermore, a light-collecting means (e.g., a microlens, etc.; the same applies hereinafter) may be formed on the device protection film below the color filter (on the side closer to the substrate), or on the color filter. The color filter may have a structure in which each color pixel is embedded in a space partitioned by partition walls, for example, in a grid pattern. In this case, the partition walls preferably have a lower refractive index than each color pixel. Examples of imaging devices having such a structure include those described in JP 2012-227478 A, JP 2014-179577 A, and WO 2018 / 043654 A. Furthermore, as shown in JP 2019-211559 A, an ultraviolet absorbing layer may be provided within the structure of the solid-state imaging element to improve light resistance. An imaging device including the solid-state imaging element of the present invention can be used in digital cameras, electronic devices with imaging functions (such as mobile phones), as well as in-vehicle cameras and surveillance cameras.

[0255] <Image display device> The film of the present invention can also be used in image display devices. Examples of image display devices include liquid crystal display devices and organic electroluminescence display devices. For definitions of image display devices and details of each image display device, see, for example, "Electronic Display Devices" (by Akio Sasaki, published by Kogyo Chosakai Co., Ltd. in 1990) and "Display Devices" (by Nobuaki Ibuki, published by Sangyo Tosho Co., Ltd. in 1990). The liquid crystal display devices are described in, for example, "Next Generation Liquid Crystal Display Technology" (edited by Uchida Tatsuo, published by Kogyo Chosakai Co., Ltd. in 1994). There are no particular limitations on the liquid crystal display devices to which the present invention can be applied, and the present invention can be applied to, for example, the various types of liquid crystal display devices described in the above-mentioned "Next Generation Liquid Crystal Display Technology."
