Abstract
A liquid crystal display (LCD) device includes a liquid crystal display panel having a matrix of liquid crystal cells defined by crossings of the data lines and the gate lines. The LCD device includes a data driving circuit for inverting a polarity of a 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 data voltages having the same polarity are respectively supplied to liquid crystal cells along one gate line in consecutive frame periods and generating the source output enable signal and the gate output enable signal.
