PROBLEM TO BE SOLVED: To provide a display device, which allows processing of an intermediate value in image detection by an image sensor attached to a display part. SOLUTION: The display device includes a plurality of display pixel parts each including a liquid crystal element, the display pixel part including a light detection means which detects incident light, a holding means which holds first analog data according to the luminance of the incident light detected by the light detection means and a data determination means which forms second data based on the first data held by the holding means, and being disposed in matrix at each intersection part between a gate line corresponding to a row and a source line corresponding to a column; a gate line drive circuit which selectively activates the gate line; a source line drive circuit which supplies display data to the source line; an output means which fetches the second data output from the data determination means as detection output data through the source line; and a detection sensitivity control means which can change the determination reference of the detection output data to the intensity of the incident light.
