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.

Abstract: A display apparatus having a light detection function is provided. The display apparatus includes a first pixel and a second pixel. The first pixel includes a first subpixel and a second subpixel. The second pixel includes a third subpixel. The first subpixel is a subpixel that emits light with the shortest wavelength (e.g., blue light or light with a shorter wavelength than blue light) in subpixels included in the first pixel. The second subpixel has a function of receiving the light emitted by the first subpixel. The third subpixel is a subpixel that emits light with the shortest wavelength in subpixels included in the second pixel. The wavelength of the light emitted by the first subpixel is shorter than the wavelength of the light emitted by the third subpixel.
