Abstract: A Gamma curve correction method for an LCD sets a ground potential of the LCD as a common voltage, and adjusts at least one of a plurality of positive Gamma voltages and a plurality of negative Gamma voltages of the LCD such that the central value of a Gamma curve established by the positive Gamma voltages and the negative Gamma voltages becomes closer to the common voltage. As a result, flickers existing in the images of the LCD are improved.
