An LCD device which can reduce the brightness deviation among pixel cells in a 2-dot inversion system. The LCD device includes at least one data line (DL1 to DLn), a plurality of first pixel cells connected in common to one side of the data line, and sequentially driven in accordance with gate signals respectively output from first gate lines (GL1 to GLm) in every period, a timing controller (321) for alternately outputting first and second-polarity data signals for display of an image, at intervals of at least two successive periods, a data modulator (322) for outputting the first and second-polarity data signals supplied from the timing controller, the data modulator modulating a grayscale value of one of the data signals respectively supplied in two successive periods from the timing controller, and outputting the modulated data signal, and a data driver (DD) for receiving the first and second-polarity data signals from the data modulator, and alternately outputting the first and second-polarity data signals at intervals of at least two successive periods, to supply the first and second-polarity data signals to the data line. |
