Abstract: A display device includes a display panel, a driving controller, and a voltage generator. The display panel includes a plurality of pixels. Each of the pixels receives a driving voltage through a first voltage line. The driving controller receives an input image signal including first to third color signals and outputs a voltage control signal for controlling a voltage level of the driving voltage based on the first to third color signals. The voltage generator provides the driving voltage to the first voltage line and determines the voltage level of the driving voltage based on the voltage control signal. The driving controller determines first to third gate-source voltages respectively corresponding to the first to third color signals and outputs the voltage control signal based on the first to third gate-source voltages.
