A display device includes: a display unit, a driver unit, and a control unit. The display unit includes a plurality of pixel units arranged in a matrix. The driver unit includes an output transistor configured to drive a plurality of scanning lines connected to the plurality of pixel units. The control unit is configured to supply to the driver unit in a display period, a signal for displaying an image on the display unit, and control a bias state of the output transistor in a display suspension period, so that an absolute value of a threshold voltage of the output transistor which is increased in the display period decreases.
