Abstract
There is provided a color filter which comprises a transparent substrate, a picture element part provided on the transparent substrate by the predetermined pattern of a plurality of colors with an ink jet system, a shading part provided on a border part of this picture element part, and a wettability-variable layer, in which the wettability can be changed, provided for forming the picture element part or the picture element part and the shading part.
Claims17
A process for producing a color filter, which comprises:
- (1) a step of forming a shading part on a transparent substrate;
- (2) a step of providing a photocatalyst-containing layer having a wettability of an energy-irradiated part which changes in a direction of reduction of a contact angle with a liquid, on a surface of the transparent substrate, on which the shading part is formed;
- (3) a step of irradiating with an energy a picture element part forming portion which is a part on the photocatalyst-containing, layer on which a picture element part is to be formed, to form an exposed part for a picture element part;
- and
- (4) a step of coloring the exposed part for a picture element part with an ink jet system to form a picture element part.
