1. A liquid crystal display device comprising:

  • a liquid crystal cell forming an image display area;

    a driver applying a voltage to said liquid crystal cell; and

    an overdrive controller controlling said driver to apply an overdrive voltage that exceeds a targeted pixel value to said liquid crystal cell;

    wherein said overdrive controller predicts a capacitance value of a pixel at one frame period later when applying a predetermined voltage to the pixel with a certain capacitance value and stores the predicted capacitance value of each pixel and calculates said overdrive voltage based on the predicted capacitance value, wherein the predicted capacitance value accounts for dynamic changes in capacitance resulting from prior applications of voltages to said liquid crystal cell.
