Abstract: A light emitting element display device with a narrow frame and high light emission efficiency is provided even when high definition is achieved. The light emitting element display device includes: a light emitting element which emits light at each of a plurality of subpixels forming one pixel; a drive transistor in which one of a source and a drain is connected to an anode of the light emitting element; and an output control circuit which selectively sets the other of the source and the drain of the drive transistor into one of a state of being connected to a power-supply voltage, a state of being connected to a reset voltage that is a lower voltage than the power-supply voltage, and a high-impedance state of not being connected to any of these voltages.
