Abstract:
1. A method of manufacturing color filter substrate, which comprises: providing a substrate; coating a first photo-resist on the substrate and performing exposure development on the first photo-resist to form a black matrix (BM) layer surrounding a plurality of divided areas; coating sequentially a second photo-resist, a third photo-resist and a fourth photo-resist and performing respective exposure development to form RGB color-resist layer in divided areas and form at least a protruding column on the BM layer; wherein the protruding column being formed by at least one of the three exposure developments; and coating a common electrode layer on the substrate, the common electrode layer covering the RGB color-resist layer and the protruding column exceeding above top surface of the common electrode layer; and performing a patterning process on the common electrode layer so that the protruding column exceeding above top surface of the common electrode layer, and exposing top surface of the BM layer not disposed with protruding column.
