Abstract
A display device with low power consumption is provided. Furthermore, a display device in which an image is displayed in a region that can be used in a folded state is provided. The conceived display device includes a display portion that can be opened and folded, a sensing portion that senses a folded state of the display portion, and an image processing portion that generates, when the display portion is in the folded state, an image in which a black image is displayed in part of the display portion.
