Abstract:
1. An image display device comprising: a display section formed by arranging pixel circuits in a matrix form, each of the pixel circuits including at least: a light emitting element; a drive transistor adapted to current-drive the light-emitting element with a drive current commensurate with a gate-to-source voltage in response to a power drive signal applied to a drain of the drive transistor via a power scan line; a holding capacitor adapted to hold the gate-to-source voltage; and a write transistor adapted to be controlled by a write signal supplied via a write signal scan line to connect a terminal of the holding capacitor to a signal line so as to set a terminal voltage of the holding capacitor to a signal line voltage; wherein: a light emission period during which the light-emitting element emits light, and non-light emission period during which the light-emitting element does not emit light, are alternately repeated; a light emission period start voltage adapted to at least start the light emission period, and a non-light emission period start voltage adapted to start the non-light emission period, are alternately output to the signal line; the terminal voltage of the holding capacitor is set by controlling the write transistor using the write signal so as to start the light emission period and the non-light emission period; the write signal is set in such a manner as to sequentially delay timings at which to set the light emission period start voltage between successive lines; the power drive signal is commonly set in units of the successive lines; and a drain voltage of the drive transistor is pulled up to high level using the power drive signal at a time other than when the terminal of the holding capacitor is connected to the signal line by the write signal in the pixel circuits in different lines.
