Abstract
A display device includes: a data line; a first scan line configured to sequentially receive a first scan pulse and a second scan pulse, each of which has a turn-on level; an emission line configured to sequentially receive a first emission pulse, a second emission pulse, a third emission pulse, and a fourth emission pulse, each of which has a turn-on level; and a pixel configured to receive the data signal according to the first and second scan pulses, the pixel being further configured to emit light based on the received data signal according to the first to fourth emission pulses, wherein the first emission pulse is generated before the first scan pulse, the second emission pulse and the third emission pulse are generated in a period between the first scan pulse and the second scan pulse, and the fourth emission pulse is generated after the second scan pulse.
