Abstract
A color filter substrate includes a light transmissive substrate, a light blocking layer, a light transmissive layer, and a color layer. The light blocking layer is formed on the light transmissive substrate. The light transmissive layer is formed along an edge of the light blocking layer on the light transmissive substrate. The color layer passes rays of visible light and is tinted a predefined color so that the rays passing therethrough exhibit a predefined color. The color layer includes a section disposed on a top surface of the light transmissive substrate in a blank area and an edge section extending from the section in the blank area over the light transmissive layer and a section of the light blocking layer. A thickness of a section of the light transmissive layer on a blank area side is less than a thickness of the light blocking layer.
