Abstract
A display device includes a gate driving part, a data driving part, a display panel and a kickback voltage compensating part. The gate driving part outputs a gate signal, and the data driving part outputs a data signal. The display panel displays an image in response to the gate signal and the data signal. A pixel voltage of the display panel is reduced by a kickback voltage varied based on a gray scale and induced when the gate signal falls. The kickback voltage compensating part compensates an image control signal externally provided to the kickback voltage compensating part for the kickback voltage to output a data control signal to the data driving part.
