Abstract:
1. A method for fabricating a color filter, said method comprising: (a) providing a plurality of exposure light sources of an exposure scanner; (b) forming a first coloration photoresist layer on a substrate plane; (c) controlling ON/OFF time of said plurality of exposure light sources to generate a first relative motion between said substrate plane and said plurality of exposure light sources, so as to perform an exposing process without using a mask to said first coloration photoresist layer to form a required pattern with a plurality of intermittent first exposure areas corresponding to first color pixels on said first coloration photoresist layer; (d) performing a development process to said first coloration photoresist layer to form a first coloration layer on said substrate plane; (e) forming a second coloration photoresist layer on the substrate plane; (f) controlling said ON/ OFF time of said plurality of exposure light sources to generate a second relative motion between said plurality of exposure light sources and said substrate plane, so as to perform an exposing process without using a mask on said second coloration photoresist layer to form a required pattern with a plurality of intermittent second exposure areas corresponding to second color pixels on said second coloration photoresist layer; (g) performing a development process to form a second coloration layer on said substrate plane; and (h) repeating said step (e) to said step (g) to form a required plurality of coloration layers on said substrate plane.
