Abstract:
The invention provides a pixel circuit that can cancel the influence of the mobility of a drive transistor. A drive transistor supplies a light-emitting element with an output current dependent upon an input voltage. The light-emitting element emits light with a luminance dependent upon a video signal in response to the output current supplied from the drive transistor. The pixel circuit includes a correction unit that corrects the input voltage held by a capacitive part in order to cancel the dependence of the output current on the carrier mobility.
