Abstract: A display device that has an excellent visibility even under strong light is provided. In the display device, a first display element that reflects visible light and a second display element that emits visible light are between a first substrate and a second substrate. The display device can display an image with high visibility by operating the first display element under strong light and operating the second display element under weak light. Furthermore, a first surface of the second substrate is provided with a touch sensor, and a second surface opposite to the first surface is provided with an anti-reflection layer. Such a structure can sufficiently reduce reflection of external light on the display surface under strong light, further increasing the visibility.
