Abstract
Ultraviolet light is selectively radiated onto a portion corresponding to each pixel on a color accepting base layer and only this portion is activated. Thus, the accepting ability (coloring ability or absorbing ability) of the coloring material for a color filter in this portion is higher than that of the other portions to which the ultraviolet light is not radiated. Alternatively, with an ultraviolet light hardening resin as the material of the color accepting base layer, the accepting layer to which the ultraviolet light is radiated and hardened is formed in an island shaped pattern. The other portions are not hardened and can be removed. The coloring material of the color filter is projected to the accepting layer formed corresponding to each pixel and only this portion can be selectively colored.
