[0358] From the viewpoint of the environment, the photosensitive composition of the present invention preferably does not substantially contain organic solvents that are aromatic hydrocarbons (toluene, xylene, benzene, chlorobenzene, etc.) Substantially not containing means that the content of such organic solvents in the photosensitive composition is 50 ppm by mass or less, preferably 30 ppm by mass or less, and more preferably 10 ppm by mass or less.
[0359] The organic solvent (P) can be used alone or in combination of two or more kinds.
[0360] The content of the organic solvent (P) is preferably such that the nonvolatile content of the photosensitive composition is 5 to 60% by mass.
[0361] The photosensitive composition of the present invention may contain components other than those described above. Examples of the other components include an acid generator, a salt generator, a curing catalyst, a semiconductor nanocrystal, a semiconductor material, an organic electroluminescent material, an insulating material, etc. The content of the other components may be appropriately set within a range that does not impair the effects of the present invention.
[0362] [Specific metal element content] The photosensitive composition of the present invention preferably has a total content of Li, Na, K, Mg, Ca, Fe, and Cr (hereinafter also referred to as specific metal elements) of 500 mass ppm or less.
[0363] A photosensitive composition in which the total amount of the specific metal elements is within the above range has excellent dispersion stability and sensitivity even after storage over time. The content of the specific metal elements can be measured by inductively coupled plasma emission spectrometry (ICP).
[0364] [Water content] The photosensitive composition of the present invention preferably has a water content of 2.0% by mass or less.
[0365] A photosensitive composition having a water content within the above range has excellent dispersion stability and sensitivity even after storage over time. The water content can be measured by a known method such as the Karl Fischer method.
[0366] [Method of producing photosensitive composition] The photosensitive composition of the present invention can be prepared by mixing the above-mentioned components. When preparing the composition, the components may be mixed at once, or each component may be dissolved or dispersed in the polymerizable compound (C) or the organic solvent (P) and then mixed successively. When a pigment is used as the colorant (A), it is preferable to disperse the pigment. For example, a dispersion is produced by adding a colorant (A), a dispersion resin (H), an organic solvent (P), etc., and carrying out a dispersion treatment. Then, an alkali-soluble resin (B), a polymerizable compound (C), a polymerization initiator (D), etc. are blended and mixed with the dispersion to produce the dispersion. The timing of blending each material is arbitrary. The dispersion process can also be carried out multiple times.
[0367] Examples of dispersing machines for carrying out the dispersion treatment include a two-roll mill, a three-roll mill, a ball mill, a horizontal sand mill, a vertical sand mill, an annular bead mill, and an attritor.
[0368] The average dispersed particle size (secondary particle size) of the particles in the dispersion is preferably from 30 to 200 nm, more preferably from 40 to 200 nm. If the particles have an appropriate particle size, a photosensitive composition having high dispersion stability is easily obtained.
[0369] The average dispersed particle size (secondary particle size) is measured, for example, using Nikkiso Microtrack UPA-EX150, which employs dynamic light scattering (FFT power spectrum method), with particle permeability set to absorption mode, particle shape set to non-spherical, and D50 particle size set to average size. The dilution solvent used for measurement is the organic solvent used for dispersion, and it is preferable to measure samples treated with ultrasonic waves immediately after sample preparation, as this tends to give results with less variation.
[0370] The photosensitive composition is preferably subjected to removal of coarse particles of 5 μm or more, preferably coarse particles of 1 μm or more, more preferably coarse particles of 0.5 μm or more, and mixed dust by means of centrifugation, filtration with a sintered filter or membrane filter, etc. The photosensitive composition of the present invention preferably does not substantially contain particles of 0.5 μm or more, and more preferably does not contain particles of 0.3 μm or less.

[0373] [Membrane manufacturing method] The method for producing the membrane is not particularly limited, and known methods can be used. In the production of the membrane of the present invention, from the viewpoint of suppressing agglomeration, the heating temperature is preferably 180° C. or less throughout the entire process, more preferably 150° C. or less. The lower limit of the heating temperature is not particularly limited, but is preferably 50° C. or more, more preferably 70° C. or more.
[0374] [Coating process] In the production of the film, first, the photosensitive composition is applied onto a substrate. The substrate may be, for example, a substrate made of a material such as glass, resin, or silicone. The glass may be colorless and transparent, or colored glass such as blue glass may be used depending on the application. The resin may be a polyester resin such as polyester terephthalate, a polyolefin resin such as polypropylene or polyethylene, a polycarbonate resin, or an epoxy resin. The thickness of the substrate is preferably 0.01 to 10 mm. An organic light-emitting layer may be formed on these substrates. Also, an imaging element such as a CCD or a CMOS may be formed on the substrate. Also, an undercoat layer may be provided on the substrate as necessary to improve adhesion with the upper layer, prevent diffusion of substances, and flatten the surface.
[0375] The coating method is not particularly limited, and any known method can be used, such as a dropping method, a slit coating method, a spray method, a roll coating method, a spin coating method, a casting coating method, an inkjet method, flexographic printing, screen printing, gravure printing, and offset printing.
[0376] The thickness of the membrane can be appropriately adjusted depending on the purpose, and is preferably 0.05 to 20.0 μm, more preferably 0.3 to 10.0 μm.
[0377] [Drying process] The method for drying the film applied to the substrate is not particularly limited, and any known method can be used, such as reduced pressure drying using a vacuum drying device, heat drying using a hot plate, an IR oven, a convection oven, or a combination of these methods.
[0378] The drying temperature and time can be appropriately adjusted. The drying temperature is preferably about 50 to 130° C., and the drying time is preferably about 5 seconds to 5 minutes.
[0379] Next, a pattern is formed. Examples of a method for forming a pattern include a photolithography method and a dry etching method. Among these, a photolithography method is preferable. When the film is used as a flat film, the step of forming a pattern is not necessary, and the entire surface can be exposed to light.
[0380] The method for forming the pattern will now be described in detail.
[0381] When a pattern is formed by a photolithography method, for example, the photosensitive composition of the present invention is applied onto a substrate, and the layer formed by drying is exposed to light in a pattern through a mask (exposure step), and the unexposed parts are removed with an alkaline developer (development step), and the pattern is then heat-treated (post-bake step).
[0382] [Exposure process] In the exposure process, the layer formed by coating and drying is exposed to a specific pattern through a mask using an exposure device such as a stepper. This allows the exposed portion to be cured. Examples of active energy rays used for exposure include ultraviolet rays such as g-rays (wavelength 436 nm), h-rays (wavelength 405 nm), and i-rays (wavelength 365 nm). Light with a wavelength of 300 nm or less 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). When using light with a specific wavelength, an optical filter can also be used. In addition, the exposure may be performed by continuous irradiation with light, or by repeating irradiation and pause of light in a short cycle (for example, on the order of milliseconds or less) (pulse exposure). In addition, a plurality of active energy rays may be used in combination, or exposure may be performed in a plurality of steps.
[0383] [Development process] Next, an alkaline development process is carried out, whereby the unexposed portions of the layer are dissolved in an alkaline developer, leaving only the hardened portions to obtain a patterned film. Examples of the alkaline developer include aqueous solutions containing alkaline compounds such as sodium hydroxide, potassium hydroxide, sodium carbonate, sodium silicate, sodium metasilicate, aqueous ammonia, ethylamine, diethylamine, dimethylethanolamine, tetramethylammonium hydroxide, tetraethylammonium hydroxide, choline, pyrrole, piperidine, 1,8-diazabicyclo-[5.4.0]-7-undecene, etc. Two or more of these alkaline compounds can be used in combination. The alkaline developer may contain a surfactant and an organic solvent in addition to the alkaline compound and water. The concentration of the alkaline developer is preferably 0.001 to 10% by mass, more preferably 0.01 to 1% by mass. The pH of the alkaline developer is preferably 11 to 13, more preferably 11.5 to 12.5. When used at an appropriate pH, it suppresses roughening and peeling of the pattern and improves the remaining film rate after development. Examples of the developing method include a dipping method, a spraying method, a puddle method, etc. The developing temperature is preferably 15 to 40° C. After the alkaline development, it is preferable to wash with pure water.
[0384] [Post-bake process] After development, a heat treatment (post-baking) is performed, which improves the resistance of the film. The heating temperature is preferably equal to or lower than 180° C., more preferably equal to or lower than 150° C. The heating time is preferably about 2 minutes to 2 hours.

Examples of the image display device include a liquid crystal display, an organic EL display, a quantum dot display, and a micro LED display. The form of the image display device is not particularly limited as long as it functions as an image display device. For example, the following liquid crystal display configuration can be given.
