The light source used for exposure is preferably a light source that generates light having a wavelength of 250 to 450 nm. For example, light less than 350 nm can be cut using a filter that cuts this wavelength range, or light near 436 nm, 408 nm, and 365 nm can be selectively extracted using a bandpass filter that extracts these wavelength ranges. Or you may. Specifically, examples of the light source include a mercury lamp, a light emitting diode, a metal halide lamp, and a halogen lamp.
Use an exposure device such as a mask aligner or a stepper because the entire exposure surface can be illuminated with parallel rays uniformly, or the photomask can be accurately aligned with the substrate on which the colored composition layer is formed. Is preferred.

A colored pattern is formed on the substrate by developing the exposed colored composition layer in contact with a developer. By the development, the unexposed portion of the colored composition layer is dissolved in the developer and removed.
As the developer, for example, an aqueous solution of an alkaline compound such as potassium hydroxide, sodium hydrogen carbonate, sodium carbonate, tetramethylammonium hydroxide is preferable. The concentration of these alkaline compounds in the aqueous solution is preferably 0.01 to 10% by mass, more preferably 0.03 to 5% by mass. Further, the developer may contain a surfactant.
