Abstract
A display device and an electronic device in which more sophistication and a high added value are realized by obtaining a read function by incorporating an imaging device, and by using a panel with small volume can be provided. A display device and an electronic device according to the invention has a first display surface and a plurality of pixels arranged in matrix over one surface of a light transmitting substrate and a second display surface over the other surface of the substrate. The plurality of pixels are each provided with a transistor, an imaging device, and a light-emitting element which emits light to the first display surface and the second display surface. The light-emitting element has two functions of serving as a light source when information of a subject is read and displaying an image. Thus, a display device according to the invention has two functions of an image sensor function to read information of a subject by using an imaging device and a display function to display an image by using the imaging device and the light-emitting element.
