ABSTRACT:
To provide a semi-transmissive type color liquid crystal display device that is capable of realizing high color reproducibility as well as increase in reflection brightness upon light transmission and upon light reflection. In display pixel elements of a color filter substrate used in the semi-transmissive type color liquid crystal display device, a color filter layer formed on a reflection part is thin and a color filter layer formed on a transmission part is thick, and a thickness of a metallic reflective film formed on the reflection part is set to 0.2 μm or more. Further, the color layer filter at the transmission part and the color layer filter at the reflection part are formed at the same time, and a continuous color filter layer is obtained.
