摘要：
A color filter substrate has reflective portions and transmissive portions. The color filter substrate includes a transmissive base; a foundation layer formed over the transmissive base; a reflective film formed over the foundation layer; a bank formed over the reflective film so as to define a deposit region; and a coloring element formed within the deposit region that is defined by the bank. The foundation layer includes a depressed portion at the transmissive portion. The thickness of the coloring element is greater at the transmissive portion than at the reflective portion. The depressed portion formed on the foundation layer allows an adequate setting of the film thicknesses of the coloring element at the reflective portion and the transmissive portion. With this structure, the brightness of and color density of the display are rendered uniform at the reflective portion and the transmissive portion.
