ABSTRACT:
A method of manufacturing a color filter in accordance with the present invention includes: (i) a latent image forming step in which, with respect to a polysilane film, first and second exposure processes having different exposure patterns and different ultraviolet light exposure amounts are carried out, and colorants are applied to the polysilane film on which first and second latent images are formed; and a coloration step in which the first and second latent images are colored by applying colorants thereto. With this, it is possible to form a first density area corresponding to transmissive image reproduction and a second density area corresponding to a second density area. Accordingly a high-quality color filter for multi-scene displays can be manufactured with fewer manufacturing steps.
