Abstract: A display device includes a display panel, a data driver, a gate driver, and a signal controller. The display panel includes a pixel connected to the gate and data lines, and the pixel includes a liquid crystal capacitor. The signal controller obtains compensation data and normal data based on input data for a still image. The signal controller apples the compensation data and normal data to the pixel during different periods of a frame. The compensation data has a value that reduces a difference of operation characteristics of liquid crystal molecules in the liquid crystal capacitor when a data voltage for the display panel changes between different polarities.
