Abstract
Appropriate image quality is maintained when a display device is powered on or when a signal is applied. After a power supply is stabilized, a pixel select gate driver section scans all pixel circuits. A final illumination on/off driver outputs illumination on/off gate signals. In this case, a start pulse for an illumination on/off shift register is started when or after an output enable signal for an illumination on/off gate signal output control circuit is output. This prevents the illumination on/off gate signals, serving as scan signals, from being improperly supplied to the pixel circuits.
