The oxygen concentration at the time of exposure can be appropriately selected, and in addition to carrying out under the atmosphere, for example, in a low-oxygen atmosphere having an oxygen concentration of 19% by volume or less (for example, 15% by volume, 5% by volume, or substantially anoxic), or exposure in a high oxygen atmosphere (for example, 22% by volume, 30% by volume, or 50% by volume) in which the oxygen concentration exceeds 21% by volume. The oxygen concentration and exposure illuminance may appropriately combine conditions, for example, an illuminance of 1 W/cm 2 at an oxygen concentration of 10 vol%, an illuminance of ² W/cm ² at an oxygen concentration of 35 vol% or the like.

Moreover, it is also preferable to irradiate light (preferably i line|wire) with a wavelength of more than 350 nm and 380 nm or less at an exposure amount of 1 J/cm< ² > or more, and expose. By exposing in this way, a coloring composition layer can fully be hardened and the pixel excellent in characteristics, such as solvent resistance, can be manufactured.

Next, the coloring composition layer after exposure is developed. That is, the unexposed part of the coloring composition layer is developed and removed, and a pattern (pixel) is formed. The image development removal of the unexposed part of a coloring composition layer can be performed using a developing solution. Thereby, the coloring composition layer of the unexposed part in an exposure process elutes to a developing solution, and only the photocured part remains. As for the temperature of a developing solution, 20-30 degreeC is preferable, for example. As for image development time, 20 to 180 second is preferable. Moreover, in order to improve residue removability, you may repeat the process of shaking off a developing solution every 60 second, and also supplying a developing solution anew several times.

As for a developing solution, an organic solvent, an alkali developing solution, etc. are mentioned, An alkali developing solution is used preferably. As an alkali developing solution, the alkaline aqueous solution (alkali developing solution) which diluted the alkali agent with pure water is preferable.

The alkali agent is preferably a compound having a large molecular weight from the viewpoint of environment and safety. 0.001-10 mass % is preferable and, as for the density|concentration of the alkali agent of alkaline aqueous solution, 0.01-1 mass % is more preferable. Moreover, the developing solution may contain surfactant further. As surfactant, the surfactant mentioned above is mentioned, A nonionic surfactant is preferable. The developer may be once prepared as a concentrate from the viewpoints of transport and storage convenience, and then diluted to a concentration required at the time of use. Although the dilution ratio is not specifically limited, For example, it can set in the range of 1.5-100 times. Moreover, it is also preferable to wash|clean (rinse) with pure water after image development. Moreover, it is preferable to supply and perform rinsing liquid to the coloring composition layer after image development, rotating the support body in which the coloring composition layer after image development was formed. It is also preferable to move the nozzle for discharging the rinse liquid from the central portion of the support to the peripheral portion of the support. At this time, in moving from the center part of the support body of a nozzle to a peripheral part, you may move, reducing the moving speed of a nozzle gradually. By rinsing in this way, in-plane unevenness of rinsing can be suppressed. Moreover, the same effect is acquired even if it reduces the rotation speed of a support body gradually, moving a nozzle from a support body center part to a peripheral part.

It is also preferable to perform an additional exposure process or a heat process (post-baking) after drying after image development. An additional exposure process and a post-baking are hardening processes after image development for making hardening complete.

When performing post-baking, 150 degrees C or less of heating temperature is preferable. As for the upper limit of heating temperature, 120 degrees C or less is more preferable, and 100 degrees C or less is still more preferable. The lower limit of the heating temperature is not particularly limited as long as curing of the composition can be promoted, but 50°C or more is more preferable, and 75°C or more is still more preferable. 1 minute or more is preferable, as for heating time, 5 minutes or more are more preferable, and 10 minutes or more are still more preferable. Although the upper limit is not specifically limited, 20 minutes or less is preferable from a viewpoint of productivity. It is also preferable to perform post-baking in the atmosphere of an inert gas. According to this aspect, thermal polymerization can be carried out with very high efficiency without being inhibited by oxygen, so that even when the pixel is manufactured at a temperature of 120° C. or less throughout the entire process, flatness is good, solvent resistance, etc. A pixel having excellent characteristics can be manufactured. Nitrogen gas, argon gas, helium gas, etc. are mentioned as an inert gas, It is preferable that it is nitrogen gas. It is preferable that the oxygen concentration at the time of a post-baking is 100 ppm or less.

When performing an additional exposure process, it is preferable to irradiate and expose with the light of wavelength 254-350 nm. As a more preferable aspect, the process (exposure before image development) of exposing the coloring composition layer in pattern shape is light with a wavelength of more than 350 nm and 380 nm or less with respect to a coloring composition layer (preferably light with a wavelength of 355-370 nm, More preferably, i Line) is irradiated and exposed, and additional exposure treatment (exposure after development) is preferably performed by irradiating and exposing the colored composition layer after development with light having a wavelength of 254 to 350 nm (preferably light having a wavelength of 254 nm). . According to this aspect, the coloring composition layer can be properly cured by the first exposure (exposure before development), and the entire coloring composition layer can be almost completely cured by the subsequent exposure (exposure after development). As a result, low-temperature conditions Also, the coloring composition layer can be fully hardened, and the pixel excellent in characteristics, such as solvent resistance, adhesiveness, and rectangular property, can be formed. Thus, when performing exposure in two steps, the coloring composition is a photoinitiator, The extinction coefficient of wavelength 365nm in methanol is 1.0x10 ³ mL/gcm or more, Photoinitiator A1, and the extinction coefficient of wavelength 365nm in methanol is 1.0. It is preferable to use the thing containing the photoinitiator A2 of 1.0x10 ³ mL/gcm or more of x10 ² mL/gcm or less, and an extinction coefficient with a wavelength of 254 nm.

Exposure after development can be performed using, for example, an ultraviolet photoresist curing device. From an ultraviolet photoresist hardening apparatus, you may irradiate light (for example, i line|wire) other than this with the light of wavelength 254-350 nm, for example.

0.03-4.0 J/cm< ² > is preferable and, as for the irradiation amount (exposure amount) in the exposure after image development, 0.05-3.5 J/cm< ² > is more preferable. It is preferable that it is 200 nm or less, and, as for the difference of the wavelength of the light used by the exposure before image development, and the wavelength of the light used by the exposure after image development, it is more preferable that it is 100-150 nm.
