a display panel;

a driving controller inserting a compensation image to first image data including a normal image to generate second image data;

a gate driver shifting an output time of a gate signal and outputting the gate signal having a shifted output time to the display panel; and

a data driver generating a data voltage based on the second image data and outputting the data voltage to the display panel,

wherein a gate shift value of a gate signal applied to a gate line for applying the compensation image is the same as a gate shift value of a gate line disposed immediately before the gate line for applying the compensation image,

wherein the gate shift value is a difference in time between a gate signal applied to pixels connected to one gate line and data voltages applied to the pixels connected to the one gate line, and

wherein the driving controller determines a compensation counting value corresponding to the compensation image.
