The process of developing the object layer. When forming pixels, it is best to conduct all processes at a temperature below 150°C. In addition, in the present invention, "the entire process is performed at a temperature of 150°C or lower" means that all processes for forming pixels using a coloring composition are performed at a temperature of 150°C or lower. This refers to the situation where a heating process is performed after developing the exposed colored composition layer, and the heating process is also performed at a temperature below 150°C. The details of each process are described below.

In the process of forming the colored composition layer, the colored composition is coated on the support to form the colored composition layer. Examples of the support include a glass substrate, a polycarbonate substrate, a polyester substrate, an aromatic polyamide substrate, a polyamide imide substrate, and a polyimide substrate. An organic light-emitting layer may be formed on the substrates. In addition, a primer layer may be provided on the substrate in order to improve the adhesion with the upper layer, prevent diffusion of substances, or flatten the surface.

During pulse exposure, the pulse width is preferably 100 nanoseconds (ns) or less, more preferably 50 nanoseconds or less, and further preferably 30 nanoseconds or less. The lower limit of the pulse width is not particularly limited, but it can be set to 1 femtosecond (fs) or more, or to 10 femtoseconds or more. The frequency is preferably 1 kHz or more, more preferably 2 kHz or more, and still more preferably 4 kHz or more. The upper limit of the frequency is preferably 50 kHz or less, more preferably 20 kHz or less, and further preferably 10 kHz or less.

The upper limit is more preferably 2.0 J/cm ² or less, and still more preferably 1.5 J/cm ² or less. In addition, the exposure illuminance can be appropriately set, and for example, 50 mW/cm ² to 10 W/cm ² is preferred. The lower limit of the exposure illuminance is more preferably 500 mW/cm ² or more, more preferably 800 mW/cm ² or more, and still more preferably 1000 mW/cm ² or more. The upper limit of the exposure illuminance is preferably 10 W/cm ² or less, more preferably 7 W/cm ² or less, and further preferably 5 W/cm ² or less.

The oxygen concentration during exposure can be appropriately selected. In addition to performing the exposure in the atmosphere, for example, it can be in a low-oxygen environment with an oxygen concentration of 19 volume % or less (for example, 15 volume %, 5 volume %, or substantially no oxygen). Exposure can also be carried out under a high oxygen environment with an oxygen concentration exceeding 21 volume % (for example, 22 volume %, 30 volume % or 50 volume %). The oxygen concentration and exposure illuminance can be combined appropriately. For example, the oxygen concentration can be 10 volume % and the illuminance is 1 W/cm ² , the oxygen concentration can be 35 volume % and the illuminance is 2 W/cm ² , etc.

In addition, it is also preferred to irradiate light (preferably i-rays) having a wavelength of more than 350 nm and less than 380 nm with an exposure amount of 1 J/cm ² or more. By such exposure, the colored composition layer can be sufficiently hardened, and a pixel with more excellent light resistance can be produced.

Next, the exposed colored composition layer is developed. That is, development removes the unexposed portion of the colored composition layer to form a pattern (pixel). The unexposed portion of the coloring composition layer can be removed by development using a developer. Thereby, the colored composition layer in the unexposed portion during the exposure process is dissolved into the developer, and only the photohardened portion remains. The temperature of the developer is preferably 20 to 30°C, for example. The development time is preferably 20 to 180 seconds. In addition, in order to improve the residue removal performance, the process of shaking off the developer every 60 seconds and supplying new developer can be repeated several times.

The concentration of the alkali agent in the alkaline aqueous solution is preferably 0.001 to 10% by mass, and more preferably 0.01 to 1% by mass. Furthermore, the developer may contain a surfactant. Examples of the surfactant include the above-mentioned surfactants, and nonionic surfactants are preferred. From the viewpoint of convenient transportation or storage, the developer can be temporarily produced as a concentrated solution and diluted to the required concentration when used. The dilution ratio is not particularly limited, but can be set in the range of 1.5 to 100 times, for example. In addition, it is also preferable to wash (rinse) with pure water after development. Furthermore, rinsing is preferably performed by supplying a rinsing liquid to the developed colored composition layer while rotating the support on which the developed colored composition layer is formed. Furthermore, it is also preferable to move the nozzle that discharges the rinse liquid from the center of the support body to the peripheral edge of the support body. At this time, when moving from the center part of the support body of the nozzle to the peripheral edge part, the moving speed of the nozzle may be gradually reduced while moving it. By performing flushing in this manner, in-plane deviation of flushing can be suppressed. In addition, the same effect can be obtained by gradually reducing the rotation speed of the support body while moving the nozzle from the center part of the support body to the peripheral part.

After development, it is also preferable to perform additional exposure processing and heat processing (post-baking) after drying. Additional exposure processing and post-baking are hardening treatments after development to achieve complete hardening.

In the case of post-baking, the heating temperature is preferably 150°C or lower. The upper limit of the heating temperature is more preferably 120°C or lower, and further preferably 100°C or lower.

The upper limit is not particularly limited, but from the viewpoint of productivity, 20 minutes or less is preferable. It is also preferable to perform post-baking in an inert gas atmosphere.

Examples of the inert gas include nitrogen, argon, helium, etc., with nitrogen being preferred. The oxygen concentration during post-baking is preferably 100 ppm or less.

When performing additional exposure processing, it is preferable to irradiate and expose with light having a wavelength of 254 to 350 nm. As a more preferable aspect, in the process of exposing the coloring composition layer in a pattern (exposure before development), the coloring composition layer is irradiated with light having a wavelength exceeding 350 nm and not more than 380 nm (preferably a light having a wavelength of 355 to 370 nm). light, more preferably i-ray), and in the additional exposure process (exposure after development), the developed colored composition layer is irradiated with light with a wavelength of 254 to 350 nm (preferably light with a wavelength of 254 nm) and exposed. For better. According to this aspect, the coloring composition layer can be appropriately hardened by the first exposure (exposure before development), and the entire coloring composition layer can be almost completely hardened by the next exposure (exposure after development). Therefore, as a result, even under low-temperature conditions, the colored composition layer can be sufficiently hardened to form a pixel excellent in characteristics such as light resistance, adhesion, and squareness. In this way, when exposure is performed in two steps, the coloring composition uses a photopolymerization initiator containing a photopolymerization initiator having an absorption coefficient of 1.0×10 ³ mL/g·cm or more at a wavelength of 365 nm in methanol. Initiator A1 and photopolymerization initiator A2 in methanol have an absorption coefficient of 1.0×10 ² mL/g·cm or less at a wavelength of 365 nm and a wavelength of 254 nm or more than 1.0×10 ³ mL/g·cm. good.

Exposure after development can be performed, for example, using an ultraviolet photoresist curing apparatus. For example, light with a wavelength of 254 to 350 nm and other light (for example, i-rays) can be irradiated from the ultraviolet resist curing device.

In addition, as the exposure source spectrum when performing the additional exposure process, a continuous spectrum is preferable. From the viewpoint of improving the light resistance of the obtained film and the adhesion to the substrate, it has a different spectral spectrum distribution from the exposure before development. Preferable examples include the following radiations (a) to (c). Among these, the radiation of (b) or (c) is preferable from the viewpoint that the light resistance of the obtained film and the adhesion to the substrate can be improved to a higher level. In addition, when the colorant contains a dye, the dye usually absorbs ultraviolet rays or short-wavelength visible rays and is photodecomposed, so radiation (c) with fewer high-intensity components on the short-wavelength side is preferable. (a) Radiation with a different spectral distribution from that of exposure before development, and the peak intensity at a wavelength of 313 nm (j ray) is 1/6 or more and less than 1/6 of the peak intensity at a wavelength of 365 nm (i ray) 3.

In addition, the lower limits of the peak intensities at the wavelength of 313 nm (j-ray) and the wavelength of 365 nm (i-ray) are not particularly limited. At this time, the exposure before development includes radiation with a wavelength of 365 nm (i rays), a wavelength of 405 nm (h rays), and a wavelength of 436 nm (g rays), and the peak intensity at a wavelength of 313 nm (j rays) is relative to the peak intensity at a wavelength of 365 nm (i rays) ), the radiation whose peak intensity does not reach 1/6 is better.

Examples of the display device include a liquid crystal display device, an organic electroluminescence display device, and the like. The definition of a display device or the details of each display device are described in, for example, "Electronic Display Equipment (by Akio Sasaki, published by Kogyo Chosakai Publishing Co., Ltd., 1990)" and "Display Equipment (by Junaki Ibuki, Sangyo Tosho Publishing Co., Ltd., released in 1989)" etc. Further, the liquid crystal display device is described in, for example, "Next Generation Liquid Crystal Display Technology (edited by Tatsuo Uchida, published by Kogyo Chosakai Publishing Co., Ltd., 1994)". There is no particular limitation on the liquid crystal display device to which the present invention can be applied. For example, the present invention can be applied to various types of liquid crystal display devices described in the above-mentioned "Next Generation Liquid Crystal Display Technology".

In addition, the organic electroluminescence display device may be a microdisplay. The diagonal length of the display surface of the microdisplay can be, for example, 4 inches or less, 2 inches or less, 1 inch or less, or 0.2 inches or less. The use of the microdisplay is not particularly limited, but examples include electronic viewfinders, smart glasses, head-mounted displays, and the like.

The organic electroluminescent display device may have a light source including a white organic electroluminescent element. As a white organic electroluminescent element, a tandem structure is preferred. The series structure of organic electroluminescent elements is described in Japanese Patent Application Laid-Open No. 2003-045676, supervised by Akiyoshi Mikami, "Forefront of Organic EL Technology Development - High Brightness, High Precision, Long Lifetime, and Skill Set-", Technical Information Institute Co., Ltd., pp. 326-328, 2008, etc. The spectrum of the white light emitted by the organic EL element is preferably one with strong maximum luminescence peaks in the blue region (430nm~485nm), green region (530nm~580nm), and yellow region (580nm~620nm). In addition to these luminescence peaks, those having a maximum luminescence peak in the red region (650nm to 700nm) are more preferred.

The organic electroluminescent display device may have a color filter. The color filter can be disposed on the base layer. In addition, in an organic electroluminescence display device that combines a color filter and a white organic electroluminescence element to extract light of three primary colors, transparent pixels can be provided to directly use the white light to emit light. In this way, the brightness of the display device can also be improved. Furthermore, the organic electroluminescence display device may have a lens on the color filter. As the shape of the lens, various shapes derived from the design of the optical system can be adopted, and examples thereof include convex shapes, concave shapes, and the like. For example, by using a concave shape (concave lens), the light condensing property can be easily improved. In addition, the lens may be in direct contact with the color filter, or other layers such as a contact layer and a planarization layer may be provided between the lens and the color filter. Moreover, the lens can also be used in the arrangement described in International Publication No. 2018/135189.
