Abstract
A display device includes a pixel including a first transistor coupled between a first node and a second node, an emission driver supplying an emission control signal at a first frequency to an emission control line, a scan driver supplying first to fourth scan signals respectively to first to fourth scan lines, a data driver supplying a data signal to a data line, and a timing controller. The first scan signal controls a timing at which a voltage of a first power source is supplied to the first node or the second node, and the second scan signal controls a timing at which a first electrode of the first transistor and a gate electrode of the first transistor are coupled to each other. The scan driver controls a bias state of the first transistor by supplying, plural times, the first and second scan signals in a non-emission period.
