Abstract: An object is to provide a highly reliable display unit having a function of sensing light. The display unit includes a light-receiving device and a light-emitting device. The light-receiving device includes an active layer between a pair of electrodes. The light-emitting device includes a hole-injection layer, a light-emitting layer, and an electron-transport layer between a pair of electrodes. The light-receiving device and the light-emitting device share one of the electrodes, and may further share another common layer between the pair of electrodes. The hole-injection layer is in contact with an anode and contains a first compound and a second compound. The electron-transport property of the electron-transport layer is low; hence, the light-emitting layer is less likely to have excess electrons. Here, the first compound is the material having a property of accepting electrons from the second compound.

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.
