Abstract
A display device includes: a display unit including a plurality of pixels and a plurality of division areas; a data driver configured to apply a data signal corresponding to image data to the display unit, and to control a slew rate of the data signal, based on a bias voltage; and a bias controller configured to control the data driver so that the slew rate of the data signal is changed for each division area, based on a luminance variation of the image data corresponding to each of the division areas.
