Abstract

According to one embodiment, a display device includes a pair of substrates including a display area in which pixels are arranged, pixel electrodes and memories provided in the pixels, signal lines supplied with digital signals, switching elements connecting the memories and the signal lines, scanning lines supplied with scanning signals, a first driver unit, and a second driver unit. The first driver unit is provided in a peripheral area around the display area, and supplies the digital signal to the signal line. The second driver unit is provided in the peripheral area, and supplies the scanning signal to the scanning line. In the display device, at least a part of the first driver unit is provided between the display area and the second driver unit.
