Patent ID: 8552945

Claim:
A liquid crystal display device comprising: a liquid crystal display panel including a common electrode containing left and right peripheral common regions and a central common region between the left and right peripheral common regions; a data driver for driving data lines of the liquid crystal display panel; a gate driver for driving gate lines of the liquid crystal display panel; and a common voltage compensating unit for generating compensating signals for compensating respective distortions of common voltages at the left and right peripheral common regions and compensating signals for compensating distortions of common voltages at the central common region by using common voltages fed back from the central and left and right peripheral common regions respectively, and supplying compensating signals corresponding to each of the plurality of common regions, wherein the common voltage compensating unit includes: a first common voltage compensating unit for compensating only the central common region based on a distortion component of a peripheral common voltage fed back from only the left and right peripheral common regions, and a second common voltage compensating unit for compensating only the left and right peripheral common regions based on a distortion component of a central common voltage fed back from only the central common region.
