Claim:
1. A liquid crystal display, comprising: a liquid crystal display panel comprising a plurality of gate lines, a plurality of data lines, and a plurality of pixels, each of the plurality of pixels comprising a pixel electrode; a gate driver connected to the plurality of gate lines and configured to apply a gate-on voltage; a data driver connected to the plurality of data lines and configured to apply a data voltage; and a signal controller configured to receive an image signal and control the gate driver and the data driver, wherein the signal controller is configured to generate two correction image data for each image signal of a single frame by referring to two compensation lookup tables and output one of the two correction image data, and the data driver is configured to apply the data voltage based on the one of the two correction image data, wherein the two compensation lookup tables are provided to make absolute values of positive and negative pixel voltages substantially identical to each other with respect to the same gray scale value, and wherein the two compensation look up tables comprise a plurality of correction data for each gray scale value, each of the plurality of correction data configured to compensate for a voltage drop at a pixel electrode caused by a parasitic capacitance formed between the pixel electrode and the a corresponding gate line of the plurality of gate lines.
