A pixel circuit in the present invention is provided with: an electrically powered light-emitting element; a drive transistor; a first capacitor; a second capacitor; a first switch for applying a reference voltage to the gate of the drive transistor; a second switch for supplying an image signal voltage to the node between the first capacitor and the second capacitor; a third switch for supplying an initialization voltage to the source of the drive transistor; and a fourth switch for causing the first capacitor to short-circuit. During an initialization period T1, the differential voltage between the reference voltage and the initialization voltage is applied to the second capacitor. During a threshold detection period T2, a current path including the drive transistor is closed, and the voltage of the second capacitor is reduced. During a writing period T3, the differential voltage between the reference voltage and the image signal voltage is applied to the first capacitor. During a light-emitting period T4, an electric current flows to the electrically powered light-emitting element.
