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 receives a supply of a current from the power supply scanner through one of the power supply lines at the first potential and flows a drive current to the light emitting element in accordance with the held signal potential, and the power supply scanner changes the one of the power supply lines from the first potential to the second potential before the sampling transistor samples the signal potential.
