A display device includes a pixel array unit in which display elements constituting pixels are arranged in a two-dimensional matrix in a row direction and a column direction. Each of the display elements includes a current-driven light-emitting unit and a drive circuit for driving the light-emitting unit. The drive circuit includes at least a write transistor for writing a video signal and a drive transistor for applying current to the light-emitting unit. A voltage is supplied to a back gate of at least the write transistor via a back gate line provided separate from a power supply line that supplies a voltage to the drive transistor.
