When an intermittent driving mode is carried out in a TFT using LIPS and α-Si for a pixel transistor, a flicker easily occurs. A display device includes a TFT including a gate, a source, and a drain; a signal line connected to the source; a pixel capacitance connected to the drain; a first power supply configured to supply a potential that breaks electricity conducted between the source and the drain to the gate; and a switch configured to supply a potential of the first power supply to the gate. The display device includes a scan period and a dwell period. The switch is turned on in the scan period, and the switch is turned off in the dwell period.
