A liquid crystal display for automatically adjusting a swing of a gamma reference voltage which is used for determining a gray scale level of a frame that is driven with a doubled frame frequency in real time is disclosed.In the liquid crystal display, a frequency converter doubles a frame frequency of an inputted frame to generate a doubled odd numbered frame and a doubled even numbered frame. A timing controller generates a gamma swing control signal which controls a swing of a gamma reference voltage which is used for determining gray scale levels of the doubled odd numbered frame and the doubled even numbered frame. And a gamma reference voltage generator generates first gamma reference voltages having a different level corresponding to a high gray scale and second gamma reference voltages having a different level corresponding to a low gray scale, and the gamma reference voltage generator inversely swings the first gamma reference voltages of high gray scale and the second gamma reference voltages of low gray scale in accordance with the gamma swing control signal for a driving period of the doubled odd numbered frame and inversely swings the first gamma reference voltages of high gray scale and the second gamma reference voltages of low gray scale in accordance with the gamma swing control signal for a driving period of the doubled even numbered frame.
