To provide an intelligent new display device integrated with an image recognition device having a pixel matrix, image sensor and peripheral circuit to drive those, that is, having both of an image recognizing function and a display function.

The display device has a plurality of pixels having active elements and arranged in a matrix, an active matrix substrate used as the electrode of the pixels, and a plurality of sensors disposed in a matrix on the active matrix substrate. The sensor has a photoelectron conversion element, and when an external image is to be read, the light passing through a light- transmitting material is used to read the information.
