Provided is a display device with photosensors that can achieve a scanner function without increasing the memory capacity for images. A display device with photosensors includes a visible light source and an invisible light source. The display device with photosensors further includes: a first photosensor that detects the amount of received light in a pixel region when the invisible light source is on; a second optical sensor that detects the amount of received light in the pixel region when the invisible light source is off; and a third photosensor that detects the amount of received light reflected from an object to be scanned, causing only display pixels respectively nearest to the third photosensors within a prescribed range in the pixel region to be in a display state, and causing other pixels in the prescribed range to be in a non-display state. Data obtained from the third photosensor is stored in a memory (205) including a region (205a) that stores therein first reference data obtained when the invisible light source is on, and a region (205b) that stores therein second reference data obtained when the invisible light source is off.
