Abstract
An image display apparatus includes a first power source line and a second power source line, which are connected to a plurality of pixel circuits, each of which includes a light-emitting device and a drive device that drives the light-emitting device; an image signal line that applies an image data potential depending on an emission brightness of the light-emitting device to the drive device; and a drive control unit (timing controller, X driver, Y driver) that controls a magnitude and an output timing of a potential applied to the image signal line, and controls a magnitude and an output timing of a potential applied to the first power source line and the second power source line, in order to perform an emission control to the respective pixel circuits all at once in all pixel circuits. The drive control unit gradually changes an image data potential of the image signal line from a first potential serving as a reference potential to a second potential serving as a constant potential so as to start the emission of the light-emitting device.
