Abstract
A liquid crystal display device includes an array substrate formed with a number of switching elements and photosensors, a countersubstrate arranged opposite to the array substrate with a gap between the array substrate and the countersubstrate, a liquid crystal layer sandwiched between the array substrate and the countersubstrate and formed from a liquid crystal material which is negative in dielectric anisotropy, and an alignment control structure set on at least one of the array substrate and countersubstrate to control the alignment state of liquid crystal molecules in the liquid crystal layer, wherein each of the photosensors being placed opposite to the alignment control structure.
