An object is to reduce noise caused by variations in characteristics of photosensors provided for each pixel in a display panel having an image capturing function by the photosensors and to provide an image with high precision. A display device includes a display panel including photosensors arranged in matrix and an image processing circuit, in which the photosensors captures a black image and an image of an object; and the image processing circuit produces an image having image data (Y−X) using image data X of the black image and image data Y of the image of the object.
