Patent ID: 7897304

Claim:
A color filter comprising: a substrate having light transmissivity; a color layer provided on a lower surface of the substrate and comprising a plurality of color pattern layers each transmitting visible light of a different color; and a phase difference control layer comprising a plurality of phase difference pattern layers which are optically anisotropic and an optically isotropic layer in which a phase difference amount is substantially zero, the phase difference control layer being provided on a lower surface of the color layer, a plurality of color differentiation regions, one for each of the different colors of the color layer, each color differentiation region comprising one of the plurality of the color pattern layers, the phase difference pattern layers and the optically isotropic layer provided on a lower surface of the color pattern layer, wherein: the phase difference control layer is configured by polymerizing and immobilizing an oriented liquid crystalline compound, a thickness of the phase difference pattern layer, a thickness of the optically isotropic layer, and a thickness of the color pattern layer are different for each of the color differentiation regions, a sum value of the thickness of the color pattern layer and the thickness of the phase difference pattern layer is constant in each color differentiation region, a first phase difference pattern layer having a phase difference provided on a lower surface of a first color pattern layer of the plurality of the color pattern layers and a second phase difference pattern layer having a phase difference provided on a lower surface of a second color pattern layer of the plurality of the color pattern layers are formed adjacent and continuous to each other in adjacent color pattern layers, and a protective film that increases flatness, chemical resistance, heat resistance and resistance to ITO is provided on a lower surface of the phase difference control layer.
