A display device includes a display panel including a pixel arranged thereon, a data driver configured to modulate video data to supply a data voltage to the pixel through a data line, a switching component configured to be turned on in response to a parking voltage enable signal to supply a parking voltage to the pixel, and a timing controller configured to control the data driver and the switching component to apply the data voltage to the pixel during a refresh period of a frame and the parking voltage to the pixel during one or more hold periods following the refresh period, wherein the timing controller adjusts a parking period for applying the parking voltage based on the luminance of the video data.
