Abstract:
A liquid crystal display device includes a liquid crystal display panel including a plurality of data lines, a plurality of gate lines, and a plurality of liquid crystal cells, the plurality of liquid crystal cells associated to a first and second liquid crystal cell groups, a data drive circuit to supply a data voltage to the data lines in response to a polarity control signal, a gate drive circuit to supply a scan pulse to the gate lines, and a polarity control circuit to generate different polarity control signals for each frame period and to control data voltage frequencies of the first and second liquid crystal cell groups to be different from each other.
