Abstract
A display device includes pixels which are connected to first scan lines, second scan lines, third scan lines, emission control lines, and data lines; a scan driver which supplies a bias scan signal to each of the third scan lines at a first frequency and supplies a scan signal to each of the first scan line and the second scan line at a second frequency which corresponds to an image refresh rate of each of the pixels; an emission driver which supplies an emission control signal to each of the emission control lines at the first frequency; a data driver which supplies a data signal to each of the data lines at the second frequency; and a timing controller which controls driving of the scan driver, the emission driver, and the data driver.
