ABSTRACT:
A color filter substrate includes a base substrate, a white light-blocking part, and a color filter layer. The white light-blocking part is formed on the base substrate. The white light-blocking part divides the base substrate into a light-transmitting area and a light-blocking area. The color filter layer is formed in the light-transmitting area. Therefore, the white light-blocking part is formed so that a boundary of the pixel part is divided and a light-blocking function is realized. Furthermore, a white luminance characteristic is enhanced.
