Abstract: A display device includes a display panel and a display panel driver. The display panel driver includes an over-driver which selects an over-driving data from an over-driving pattern which moves to a predetermined direction, generates a reference line based on a first polynomial expression generated based on the over-driving data, and generates an over-driving data lookup table by moving the reference line, a data driver which outputs a data signal generated based on the over-driving data lookup table to the data line of the display panel, and a gate driver which outputs a gate signal to the gate line of the display panel.
