Liquid crystal display device and driving method thereof

A liquid crystal display device comprising:

• a liquid crystal display panel having a plurality of data lines that cross a plurality of gate lines to define a matrix of liquid crystal cells;
• a data driving circuit for inverting a polarity of data voltage in response to a polarity control signal, and supplying the polarity-inverted data voltage to an associated one of the data lines in response to a source output enable signal;
• a gate driving circuit for sequentially supplying a scan voltage to each of the gate lines in response to a gate output enable signal;
• and
• a controller for modulating the polarity control signal such that the polarity of the data voltages respectively supplied to each of the liquid crystal cells along a selected one of the gate lines in a pair of consecutive frames periods of each repeating sequence of a predetermined number of frames periods, and wherein the polarity of the data voltages respectively supplied to each of the liquid crystal cells along the selected one of the gate lines in the remaining frame periods of each repeating sequence of the predetermined number of frames periods alternates for each frame period in the repeating sequence while the scan voltage is supplied to the selected gate line, and for generating the source output enable signal and the gate output enable signal.
