Claim:
1. A liquid crystal display device comprising: a gamma generator and a liquid crystal display panel; wherein the gamma generator comprises a first storage unit and a second storage unit; the first storage unit stores a group of first gamma voltage values, and the second storage unit stores a group of second gamma voltage values; wherein the first gamma voltage values are positive gamma voltage values, the second gamma voltage values are negative gamma voltage values; or, the first gamma voltage values are negative gamma voltage values, the second gamma voltage values are positive gamma voltage values; according to a control of a polarity inversion signal, the gamma generator periodically obtains the group of the first gamma voltage values from the first storage unit, or the gamma generator periodically obtains the group of the second gamma voltage values from the second storage unit; the liquid crystal display panel displays an image according to the group of the first gamma voltage values and/or the group of the second gamma voltage values; the first storage unit further stores a first gamma value corresponding to the group of the first gamma voltage values, and the second storage unit further stores a second gamma value corresponding to the group of the second gamma voltage values; wherein the first gamma value equals to the second gamma value.
