    Abstract: A display device and a driving method thereof are disclosed. In one aspect, the display device includes a display panel including a plurality of pixel rows, a data driver configured to transfer data voltages to the display panel, a gate driver configured to transfer gate signals to the display panel, and a signal controller configured to control the data driver and the gate driver. The pixel rows are divided into i (i is a natural number of 2 or more) pixel row groups including a plurality of pixel rows, respectively. The display panel displays one still image for one frame set including the i sequential frames, and each of the i pixel row groups is charged by receiving the data voltage for each frame of the frame set, and the frames in which the i pixel row groups are charged are different from each other.
