Abstract: A display device that can switch between normal display and see-through display is provided. Visibility in see-through display is improved. A liquid crystal element overlaps with a light-emitting element. The light-emitting element, a transistor, and the like overlapping with the liquid crystal element transmit visible light. When the liquid crystal element blocks external light, an image is displayed with the light-emitting element. When the liquid crystal element transmits external light, an image displayed with the light-emitting element is superimposed on a transmission image through the liquid crystal element.
