Abstract

To display a high-quality video regardless of a usage environment. To provide a display device which is lightweight and less likely to be broken. To reduce power consumption of the display device. The display device includes a first display element, a first transistor connected to the first display element, a second display element, and a second transistor connected to the second display element. The first display element is a reflective display element. The first display element and the first transistor are bonded to the second display element and the second transistor with an adhesive layer. Light from the second display element is extracted to the display surface on the first display element side. The light is condensed or guided by a light-condensing means or a light-guiding means provided in a path of the light from the second display element to the display surface.
