A display device includes a display panel including gate lines, data lines, and pixels; a gate driver that provides gate signals to the pixels through the gate lines; a data driver that provides data signals to the pixels through the data lines; and a timing controller that obtains pre-charging gray scale values based on gray scale values of the pixels. The gate driver simultaneously supplies the gate signals to the gate lines in a first period, and sequentially supplies the gate signals to the gate lines in a second period. The data driver supplies data signals corresponding to the pre-charging gray scale values to the data lines in the first period, and supplies data signals corresponding to the gray scale values of the pixels to the data lines in the second period.
