Abstract
In a display device that can use a low frequency drive method, in the case of low frequency drive, in a data correction unit (23) of a display control circuit (200), a pixel grayscale value is set such that the differential value between the potential difference between the pixel electrode and the common electrode when a voltage of positive polarity is applied and the potential difference between the pixel electrode and the common electrode when a voltage of negative polarity is applied becomes larger than during normal drive. With this, a correction amount (shift amount) is made larger during low frequency drive than during normal drive, whereby flickers and ghosting during low frequency drive are prevented.
