ABSTRACT:
A color filter substrate for a liquid crystal display device includes a color layer, a photo spacer and a counter electrode disposed on the substrate, and an alignment control protrusion is disposed on the counter electrode for controlling alignment of liquid crystal. A manufacturing method for the color filter substrate includes the step of forming an opening by laser irradiation in a region of the counter electrode corresponding to an absent portion occurring in the alignment control protrusion. The manufacturing method is also applicable to an active matrix substrate for a liquid crystal display device. The manufacturing method can effectively correct a defect if one occurs in the alignment control protrusion.
