Abstract: An object is to provide a display device having a function of emitting visible light and infrared light and an imaging function. Another object is to increase the definition without changing the density of imaging elements while the high resolution of an image displayed on a display device is kept. The display device has a layout in which a light-receiving region of an imaging element is provided between light-emitting regions of a plurality of light-emitting elements over one substrate. In the imaging function of the display device, as a means for increasing the definition of a captured image, the definition is increased without changing the density of imaging elements by capturing an image by time division.
