Abstract:
A backlight source has a spectral distribution such that luminances of red and green light are stronger than luminance of blue light. A color filter includes a blue coloring layer that can best transmit a blue light, a red coloring layer that can best transmit a red light, a green coloring layer that can best transmit a green light, and a porous layer in which penetration holes are formed so as to penetrate therethrough in its thickness direction. The blue coloring layer is formed so as to be thicker than the red and green coloring layers. A liquid crystal layer is formed so as to be thinner in a portion facing the blue coloring layer than a portion facing the red and green coloring layers. The porous layer is formed from the same material and to have the same thickness as the blue coloring layer.
