Abstract
A display device with an imaging function is provided. A high-resolution imaging device or display device is provided. The display device includes first to third switches, first and second transistors, a capacitor, first and second wirings, and a light-emitting and light-receiving element. One electrode of the first switch is electrically connected to the first wiring, and the other electrode is electrically connected to a gate of the first transistor and one electrode of the capacitor. One electrode of the second switch is electrically connected to one of a source and a drain of the first transistor, one electrode of the light-emitting and light-receiving element, and the other electrode of the capacitor, and the other electrode of the second switch is electrically connected to a gate of the second transistor and one electrode of the third switch. The other electrode of the third switch is electrically connected to the second wiring. The light-emitting and light-receiving element has a function of emitting light of a first color and a function of receiving light of a second color.
