Abstract
A liquid crystal display device of the present invention includes a liquid crystal display panel (10) in which a liquid crystal layer (13) is arranged between an active matrix substrate (11) and a counter substrate (12). A plurality of optical sensors (16) are provided in respective image display regions of the liquid crystal display panel (10), each of the optical sensors (16) having a light receiving section (16d) for detecting transmitted light through a panel surface of the liquid crystal display panel (10). The liquid crystal display panel (10) is a transflective type panel and the optical sensors (16) are provided in respective reflective display regions (R) of the transflective type panel. Further, a reflective electrodes (34) provided above the respective optical sensors (16) serve as light shielding layers so as to shut out light which enters the light receiving section (16d) in an oblique direction. Moreover, an aperture (34a) is provided in a part of each of the reflective electrodes (34) so that the light receiving section (16d) can detect light from directly above.
