Abstract
Disclosed herein is a process for producing a color filter, which comprises the steps of forming a black matrix pattern with a resin on a transparent base, conducting a surface-state-modifying treatment to increase surface energy of the surface of the base at areas corresponding to spaces of the black matrix pattern, and applying inks to the portions of the base corresponding to the spaces of the black matrix pattern.
