Patent ID: 8013955

Claim:
A liquid crystal display, comprising; an active matrix substrate in which a plurality of pixels are arranged in matrix form; a counter substrate in which a color filter is provided, wherein the active matrix substrate includes a plurality of photodiodes within a display region, each of the plurality of pixels includes two or more sub-pixels, each of the sub-pixels includes a reflective electrode that reflects light incident from a viewer side, each of the reflective electrodes including an opening through which a photodiode light detection region is exposed, the color filter includes colored areas that are in one-to-one correspondence with the sub-pixels, wherein, in a given sub-pixel, the color filter comprises a colored area and a high-transmittance area defined in the colored area, the high-transmittance area having a higher transmittance than the colored area, and wherein the high-transmittance area in the sub-pixel at least partially overlaps the photodiode light detection region at the opening as viewed from the viewer side.
