Abstract
A display device includes: a pixel; a scan driver configured to supply a scan signal to the pixel through a scan line; an emission driver configured to supply an emission control signal comprising a plurality of gate-on level signals to the pixel through an emission control line in one frame, the plurality of gate-on level signals for generating emission periods of the pixel; a data driver configured to supply a data signal to the pixel through a data line; and a controller configured to control a waveform of the emission control signal, wherein a length of a first emission period of the emission periods is longer than a length of another emission period of the emission periods.
