The oxygen concentration and exposure illuminance may be appropriately combined. For example, an illuminance of 1 W/cm ² at an oxygen concentration of 10% by volume and an illuminance of 2 W/cm ² at an oxygen concentration of 35% by volume.

It is also preferable to irradiate with light having a wavelength of more than 350 nm and less than or equal to 380 nm (preferably i-line) at an exposure amount of 1 J/cm ^{2 or more} . By exposing in this manner, the colored composition layer can be sufficiently cured, and a pixel having more excellent light resistance can be produced.

Next, the colored composition layer after exposure is developed. That is, the unexposed portion of the colored composition layer is removed by development to form a pattern (pixels). The development and removal of the unexposed portion of the colored composition layer can be performed using a developer. As a result, the unexposed portion of the colored composition layer in the exposure step is eluted into the developer, leaving only the photocured portion. The temperature of the developer is preferably 20 to 30° C., for example. The development time is preferably 20 to 180 seconds. Further, in order to improve the residue removability, the step of shaking off the developer every 60 seconds and then supplying new developer may be repeated several times.

Although the dilution ratio is not particularly limited, it can be set, for example, in the range of 1.5 to 100 times. It is also preferable to wash (rinse) with pure water after development. Rinsing is preferably carried out by supplying a rinsing solution to the developed colored composition layer while rotating the support on which the developed colored composition layer is formed. It is also preferable to move the nozzle for discharging the rinsing liquid from the central portion of the support to the peripheral portion of the support. At this time, when moving the nozzle from the center of the support to the periphery, the moving speed of the nozzle may be gradually decreased. By performing rinsing in this manner, in-plane variations in rinsing can be suppressed. A similar effect can be obtained by gradually decreasing the rotation speed of the support while moving the nozzle from the center of the support to the periphery.

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

When the additional exposure process is performed, it is preferable to irradiate light with a wavelength of 254 to 350 nm for exposure. In a more preferred embodiment, the step of exposing the colored composition layer in a pattern (exposure before development) is performed with respect to the colored composition layer with light having a wavelength of more than 350 nm and 380 nm or less (preferably light with a wavelength of 355 to 370 nm, More preferably i-line) is irradiated and exposed, and the additional exposure treatment (exposure after development) is performed on the colored composition layer after development with light having a wavelength of 254 to 350 nm (preferably light having a wavelength of 254 nm). ) is preferably used for exposure. According to this aspect, the coloring composition layer can be moderately cured in the first exposure (exposure before development), and the entire coloring composition layer is almost completely cured in the next exposure (exposure after development). As a result, even under low temperature conditions, the colored composition layer can be sufficiently cured to form pixels having excellent properties such as light resistance, adhesion and rectangularity.

Therefore, the radiation of (c), which has less high-intensity components on the short-wavelength side, is preferred.
