摘要： With the related art, the choice of locations for disposition of ambient light photosensors is narrow, and consequently it is difficult to respond flexibly to user specifications for differing structures of the case. With a display device of the invention however, ambient light photosensors can be disposed laterally and longitudinally, enabling the intensity of light in longitudinal or lateral directions to be sensed at the same levels. Also, bridge-connecting together the longitudinally-disposed ambient light photosensors enables ambient light photosensors to be disposed close to the outer periphery of the display area in both the longitudinal and lateral directions. Thereby, the problems with the related art can be resolved.

The photodetector unit is disposed on a first surface of the TFT substrate 2 that is in contact with the liquid crystal layer, and the surface of the photodetector unit except for the semiconductor layer 19L and its periphery is covered by a light-shielding layer 21. It is therefore possible to provide an LCD in which malfunction or reduced sensitivity of its ambient light photosensor due to light from its backlights is prevented with a simple structure.
