Abstract

A display apparatus includes a display panel, a gamma reference voltage generator and a data driver. The gamma reference voltage generator is configured to generate a gamma reference voltage. The gamma reference voltage includes a gamma amplifier configured to output the gamma reference voltage. The data driver is configured to generate a data voltage based on the gamma reference voltage and to output the data voltage to the display panel. A polarity of an offset voltage of the gamma amplifier is inverted alternately in a unit of one frame and in a unit of two frames.
