Abstract:
1. A display device comprising: a pixel array unit including a plurality of pixels, and power supply lines; and a power supply scanner for supplying a power supply voltage switching between first and second potentials to each of the power supply lines, wherein a given one of the plurality of pixels includes a light emitting element, a sampling transistor, a driver transistor, and a holding capacitor, wherein the sampling transistor samples a signal potential to be held in the holding capacitor, the driver transistor is connected to the light emitting element and is configured to control a drive current flowing through the light emitting element in accordance with the held signal potential, and the power supply scanner causes the light emitting element to be in a non-emission state by changing one of the power supply lines from the first potential to the second potential before the sampling transistor samples the signal potential.
