LIQUID CRYSTAL DISPLAY DEVICE AND COLOR FILTER SUBSTRATE

摘要

A liquid crystal display device is provided with a touch panel function, in which an array substrate (2) and a color filter substrate (4) are faced each other via a liquid crystal layer (3). The color filter substrate (4) includes: a transparent substrate (11); first and second transparent electrode layers (12a, 12b); a color filter (CF); and a transparent resin layer (14). The first and second transparent electrode layers (12a, 12b) are respectively formed on first and second surfaces of the transparent substrate (11) for touch sensing. The color filter (CF) is formed on the first transparent electrode layer (12a), including a red filter, a green filter and a blue filter. The transparent resin layer (14) is formed on the color filter (CF). In the liquid crystal display device, the second transparent electrode layer (12b) is formed on a display surface side and the transparent resin layer (14) is formed on a liquid crystal layer (3) side. The total film thickness of the color filter (CF) and the transparent resin layer (14) is within a range approximately from 2.5 µm to 9 µm. The liquid crystal layer (3) includes liquid crystal molecules (L) having negative dielectric anisotropy and an initial state alignment which is parallel to a substrate surface. The liquid crystal molecules rotate parallel with respect to the substrate surface when a liquid crystal drive voltage is applied.
