Color filter, semi-transmissive semi-reflective liquid-crystal display device, method for forming phase difference control layer, and method for manufacturing color filter

摘要

A color filter of the present invention comprises a substrate having light transmissivity, a color layer provided on the lower surface of the substrate and comprising a plurality of color pattern layers, each transmitting visible light of different color, and a phase difference control layer comprising a plurality of phase difference pattern layers and optically isotropic layers and provided on the lower surface of the color layer. A color differentiation region comprising a color pattern layer and a phase difference pattern layer and an optically isotropic layer that are provided on the lower surface of the color pattern layer is formed for each color of the color pattern layer, and the thickness of the phase difference pattern layer and the thickness of the color pattern layer are respectively different for each color differentiation region.
