To prevent deterioration in display quality, occurring when large size, high definition display device is constituted.

A pixel circuit 11 is equipped with: a light emitting element EL; alight emission control switch element SW5; a current control circuit 15 for supplying a drive current corresponding to gradation display data to the light emitting element EL through the light emission control switch SW 5; and a voltage control circuit 16 including a capacitance element C1 storing voltage corresponded to gradation display data and controlling ON, OFF of the light emission control switch element SW5 in accordance with stored voltage. When the gradation display data is data for displaying luminance below the prescribed value to the light emitting element, the current control circuit 15 supplies a fixed drive current corresponding to the gradation display data for displaying the prescribed luminance to the light emitting element EL, while the voltage control circuit 16 controls an ON time of the light emission control switch element SW5 in accordance with the stored voltage.
