Liquid crystal display with opening in reflective electrode

Abstract

A liquid crystal display is provided that can achieve an improvement in sensitivity of a photodiode disposed within a display region of an active matrix substrate. To this end, a liquid crystal display is used that includes: an active matrix substrate 1 in which a plurality of pixels are arranged in matrix form; and a counter substrate in which a color filter is provided. In the liquid crystal display, the active matrix substrate 1 includes a photodiode 11 within a display region, and the color filter includes colored areas 6a to 6c that are in one-to-one correspondence with sub-pixels 5a to 5c that constitute a pixel. Each of the colored areas 6a to 6c includes a high-transmittance portion 31 having a transmittance higher than a transmittance of a periphery of the high-transmittance portion 31. Of these colored areas 6a to 6c, the colored area 6a is formed so that the high-transmittance portion 31 positionally coincides with an i layer 13 (light detection region) of the photodiode 11 in a thickness direction of the liquid crystal display.
