ABSTRACT:
A color filter substrate comprising a substrate, a black matrix and a plurality of color filter patterns is provided. The black matrix is disposed on a rough surface of the substrate to define a plurality of sub-pixel regions. Each one of the color filter patterns is disposed in one of the sub-pixel region and touch the rough surface. When the color filter patterns are formed in the sub-pixel regions, the contacting area between the color filter patterns and the substrate is increased owing to the rough surface of the substrate. Thus, the adhesion between the color filter patterns and the substrate within the sub-pixel regions are enhanced.
