Patent ID: 8179483

Claim:
A liquid crystal display device comprising: a liquid crystal display panel in which a liquid crystal layer is arranged between an active matrix substrate and a counter substrate, a plurality of optical sensors being provided in respective image display regions of the liquid crystal display panel, each of the optical sensors having a light receiving section for detecting light transmitted through a surface of the liquid crystal display panel, a light shielding layer being provided above each of the optical sensors so as to shut out light which enters the light receiving section in an oblique direction, an aperture being provided in a part of each of the light shielding layers, via which aperture each of the optical sensors can detect light which enters each of the light receiving sections from directly above, and wherein the optical sensors and the light shielding layer are on the active matrix substrate, so that a pixel electrode on the active matrix substrate is located between at least one of the optical sensors and the light shielding layer.
