1. A liquid crystal display device comprising:

  • a liquid crystal display panel including a plurality of data lines crossing a plurality of gate lines and liquid crystal cells arranged in a matrix;

    a timing controller generating a polarity control signal, deciding if a predetermined weak pattern data is input, and shifting a phase of the polarity control signal in a next frame period following a frame showing the weak pattern data when the weak pattern data is input;

    a data driving circuit reversing the polarity of the data voltage in response to the polarity control signal and supplying to the data lines; and

    a gate driving circuit supplying a gate pulse to the gate lines sequentially.
