Abstract
Disclosed herein is a process for producing a color filter substrate for picture device constructed by selectively arranging light-shielding members and a plurality of coloring members different in spectral characteristics from each other on a transparent base, which comprises the steps of forming a water-repellent layer composed of a silane coupling agent on the base on which the light-shielding members are partially formed, exposing the surface of the base to oxygen plasma, and arranging a plurality of the coloring members different in spectral characteristics from each other on transparent regions of the base.
