Image display device having a reset switch for setting a potential of a capacitor to a predetermined reference state
Abstract:
Provided is an image display device including: a plurality of pixel scanning lines; a plurality of signal lines; and a plurality of pixel circuits corresponding to intersections between the pixel scanning lines and the signal lines. Each of the pixel circuits includes: a driver transistor; a light emitting element for emitting light based on the current supplied from the driver transistor; a pixel switch for generating a potential based on an image signal and a scanning signal; a capacitor element for controlling the driver transistor based on a potential difference caused by the potential supplied from the pixel switch; and a reset switch for setting a potential at an end of the capacitor element to a predetermined state based on a scanning signal supplied from one of the pixel scanning lines preceding the scanning signal which corresponds to the corresponding one of the plurality of pixel circuits.
