Abstract
Control of a light emission period of a light-emitting element results in higher visibility. A display device includes a signal line, a first scan line, a second scan line, and a pixel circuit. The pixel circuit includes a light-emitting element, a first transistor, a second transistor, a third transistor, and a capacitor. The second transistor is turned on by application of voltage that is lower than voltage applied to the first scan line to the second scan line after the second transistor is turned off by second voltage. Thus, a gate of the third transistor is controlled by the voltage applied to the second scan line. The display device has a function of controlling the light emission period by turning off the third transistor by the second scan line.
