摘要： A display device includes an image analyzing part which determines whether current frame image data includes a crosstalk pattern, and a gamma voltage generator which generates current frame gamma data by applying the asymmetric gamma when the current frame image data do not include the crosstalk pattern, and generates the current frame gamma data by applying a symmetric gamma when the current frame image data includes the crosstalk pattern. The positive polarity and negative polarity data voltages of the asymmetric gamma are asymmetric with each other for each of the grayscales, and the positive polarity and negative polarity data voltages of the symmetric gamma are symmetric with each other for each of the grayscales.
