A light extraction efficiency is increased in a display device having a plurality of display elements. The display device includes a first display element and a second display element over the first display element, and the first display element has a convex-concave shape. The convex-concave shape overlaps with a first opening provided in a reflective electrode of the second display element. A user can see an image that combines the display from the first display element and the display from the second display element. The convex-concave shape increases the light extraction efficiency of the first display element. The second display element is electrically connected to a transistor through a second opening provided in any layer of the first display element. The second display element can be provided close to the first display element.
