Abstract:
A display device having a photosensor which exhibits excellent photoelectric conversion efficiency is provided. In a display device which forms photosensors on a substrate thereof, the photosensor is formed by sequentially stacking a gate electrode, a gate insulation film and a semiconductor layer in such an order or in an opposite order from a substrate side, and electrodes are connected to both sides of the semiconductor layer respectively, the semiconductor layer is formed of a stacked body consisting of a crystalline semiconductor layer and an amorphous semiconductor layer, and the crystalline semiconductor layer is arranged on the gate insulation film side.
