The present invention relates to an display panel driving apparatus which comprises a gate drive unit and a data drive unit. The gate drive unit outputs a gate signal to a gate line and a gate line of the display panel including a data line. The data drive unit outputs a data signal to the data line, outputs a moving image data to the display panel during Nth (N is a natural number) frame, outputs a moving image data to the display panel during (N+1)th frame, and controls a polarity of the moving image data displayed on the display panel during (N+2)th frame by comparing a polarity of the moving image data of Nth frame and a polarity of the moving image data of (N+1)th frame. Accordingly, it is possible to improve the display quality of the display device.;COPYRIGHT KIPO 2015
