Display device

摘要

According to one embodiment, a display device includes first interconnects, second interconnects, third interconnects, fourth interconnects, switch elements, pixel electrodes, a first insulating layer, a display layer, and a control unit. Each of the switch elements is electrically connected to one of the first interconnects and one of the second interconnects. The pixel electrodes are electrically connected respectively to the switch elements. The first insulating layer is provided between the second and third interconnects. The fourth interconnects are separated from the first to third interconnects, the switch elements, and the pixel electrodes. The display layer is provided between the pixel electrodes and the fourth interconnects. The display layer performs an optical operation of one of a light emission and a change of an optical characteristic. The control unit performs a sense operation, a first display operation, a second display operation, and a pre-display operation.
