Abstract:
1. A liquid crystal display device comprising: an array substrate including a plurality of switching elements, pixel electrodes electronically connected to a respective one of the switching elements, and photosensors; a counter-substrate arranged opposite to the array substrate with a gap between the array substrate and the counter-substrate, the counter-substrate having at least one counter-electrode opposed to the pixel electrodes; a liquid crystal layer sandwiched between the array substrate and the counter-substrate and formed from a liquid crystal material which is negative in dielectric anisotropy; and an alignment control structure defined by gaps between the pixel electrodes of the array substrate and stripe-shaped slits in the at least one counter-electrode of the counter-substrate to control an alignment state of liquid crystal molecules in the liquid crystal layer, each of the photosensors being arranged to lie above and overlap a respective one of the slits, a width of each of the photosensors being greater than a with of the respective one of the slits, and a length of each of the photosensors being smaller than a length of the respective one of the slits.
