ABSTRACT:
A liquid crystal display device includes a liquid crystal display panel including a plurality of data lines to which a data voltage is supplied, a plurality of gate lines to which a gate pulse is supplied, and a plurality of liquid crystal cells, a data drive circuit to invert a polarity of the data voltage in response to a polarity control signal and to output the data voltage to the data lines in response to a source output enable signal, a gate drive circuit to supply the gate pulse to the gate lines, and a POL/SOE logic circuit to invert the polarity control signal for every frame period except at Nth-multiple frame period (where N is a positive integer), wherein the POL/SOE logic circuit controls the polarity control signal at every Nth-multiple frame period such that the polarity of the data voltage is the same as the previous frame period and controls a pulse width of the source output enable signal at every Nth-multiple frame period to be longer than for the other frame periods.
