ABSTRACT:
In the present invention, a provision of a method for manufacturing a color filter capable of forming a highly sophisticated pattern, to be formed easily at a low cost is desired. The present invention achieves the above mentioned object by providing a method for manufacturing a color filter comprising:(1) forming a light shielding part on a transparent base material;(2) forming a wettability changeable layer which the wettability changes by the function of a photocatalyst, on the surface of the transparent base material on the side with the light shielding part formed;(3) placing the photocatalyst containing layer of the photocatalyst containing layer side substrate which is the photocatalyst containing layer containing a photocatalyst formed on the base member, and the wettability changeable layer with a gap of 200 μm or less, and irradiating an energy from a predetermined direction to form a pixel part forming part comprising a lyophilic area where the contact angle to a liquid is lowered compared with the state before the energy irradiation to the wettability changeable layer, in a pattern; and(4) coloring the pixel part forming part by the ink jet method so as to form a pixel part.
