ABSTRACT:
A display device includes a pixel array unit and a driver unit. A sampling transistor samples a signal potential to hold the signal potential in a holding capacitor. A driver transistor flows a drive current to a light emitting element in accordance with the signal potential held. A power supply scanner in the driver unit changes a power supply line from a first potential to a second potential before the sampling transistor samples the signal potential. A main scanner in the driver unit makes the sampling transistor conductive to apply a reference potential from the signal line to the gate of the driver transistor and to set the source of the driver transistor to a second potential. The power supply scanner changes the power supply line from the second potential to the first potential to hold a voltage corresponding to a threshold voltage off the driver transistor in the holding capacitor.
