Abstract

Disclosed is a liquid crystal display wherein a photodiode is prevented from responding to the illumination light, while suppressing occurrence of dark current in the photodiode. Specifically disclosed is a liquid crystal display comprising a liquid crystal display panel (4) and a backlight. The liquid crystal display panel (4) comprises an active matrix substrate (1), a liquid crystal layer (2) and a counter substrate (3). A plurality of pixels respectively have three sub-pixels (5a-5c), and a color filter provided on the counter substrate (3) has colored layers (6a-6c) respectively corresponding to the sub-pixels. In this liquid crystal display, the backlight is so arranged as to illuminate the liquid display panel (4) from the counter substrate side. The active matrix substrate (1) comprises a photodiode (20) within a display region. The photodiode (20) has such a characteristic that the sensitivity increases as the wavelength of an incident light is shorter, and is so arranged that its light sensing region overlaps a red colored layer (6c) in the thickness direction of the liquid crystal display.
