Provided is a display device including a gate driver configured to output a plurality of gate signals to a plurality of gate lines during each of a first frame and a second frame, and a display panel configured to display a first image during the first frame and to display a second image during the second frame, the second frame being longer in duration than the first frame, wherein each of the gate signals includes a high interval having a first voltage level and a low interval having a second voltage level lower than the first voltage level, and wherein the second voltage level of the gate signals during the second frame is lower than the second voltage level of the gate signals during the first frame.
