In the apparatus, a pre-charge voltage generator generates a pre-charge voltage allowing a gamma voltage to be higher than a target voltage in a certain time interval every one horizontal period.

Accordingly, a gamma voltage including a pre-charge voltage higher than the target gamma voltage is applied to improve a charge characteristic of the pixel, thereby preventing a charged voltage difference from being generated between the horizontal and vertical pixels.
