Abstract
A display device includes a pixel, a scanning line, a signal line, and a drive circuit configured to be supplied with a first power supply voltage signal of a positive value and a second power supply voltage signal of a negative value. The drive circuit includes: a gate driver configured to supply a scanning signal to the scanning line; a signal line selection circuit configured to supply a pixel signal to the signal line; and a display control circuit. The display control circuit is configured to, at first time in a power-off sequence, supply the first power supply voltage signal to the scanning line, supply a GND potential to the common electrode, and supply an adjustment potential of a positive value to the signal line. The display control circuit is configured to supply the GND potential to the scanning line at second time after the first time.
