Abstract
A liquid crystal display of the present invention comprises a panel on which are formed a plurality of thin film transistors, a plurality of gate lines connected to gate electrodes of the thin film transistors, a plurality of data lines connected to source lines of the thin film transistors, a gate driver that applies a gate signal to the gate lines of the panel, a data voltage generator that generates data voltages which has many voltage levels, a data driver that applies to the data lines a data voltage for displaying picture signals on the liquid crystal display, a common electrode voltage generator that generates a common electrode voltage applied to a common electrode of the panel, a compensator for a distortion of common electrode voltage that is connected between the panel and the data voltage generator and compensates for the distortion of common electrode voltage by changing the data voltage. The crosstalk phenomenon of the LCD can be decreased in accordance with the present invention.
