ABSTRACT:
A method of making a color filter apparatus prevents the formation of residual portions of resist film used to form a plurality of different color filters included in the color filter apparatus. In the method of forming the color filter apparatus, a surface treatment of a transparent substrate is carried out between the steps of sequentially forming red, green and blue filters on the upper portion of the transparent substrate. The surface treatment prevents the formation of residual portions of resist films at the time of forming the filters.
