Abstract: In a display device that performs external compensation, pixel circuits are classified into specific and general pixel circuits. When display is restarted, a current measurement circuit, along with a drive circuit, measures a current flowing through a drive transistor in the specific pixel circuit as a first current. A correction circuit obtains a recovery ratio for a characteristic of the drive transistor on the basis of an amount of the first current and corrects a video signal for each of the specific and general pixel circuits using the recovery ratio. Thus, when display is restarted, a suitably compensated image is displayed.
