Abstract

A display device includes a display unit including luminescence pixels each including a luminescence element and a driving transistor configured to supply a current to the luminescence element to cause the element to emit light, a signal line driving circuit configured to supply a voltage applied between a gate and a source of the driving transistor, and a control circuit configured to apply a certain voltage between the gate and the source of the driving transistor by controlling the signal line driving circuit and the display unit when a power supply to the signal line driving circuit is stopped. The control circuit applies the certain voltage between the gate and the source of the driving transistor so that a recovery of a shift amount of a threshold voltage of the driving transistor is suppressed, the recovery being made when the power supply to the signal line driving circuit is stopped.
