1. A liquid crystal display device comprising:

  • a plurality of data lines;

    a plurality of gate lines intersecting the plurality of data lines;

    a plurality of pixel electrodes respectively arranged at intersections between the plurality of data lines and the plurality of gate lines;

    a plurality of switching elements, each including a control terminal connected to a corresponding one of the plurality of gate lines, a first terminal connected to a corresponding one of the plurality of pixel electrodes, and a second terminal connected to a corresponding one of the plurality of data lines;

    a plurality of storage capacitor lines respectively corresponding to the plurality of gate lines;

    a plurality of storage capacitors, each including a first capacitor electrode connected to a corresponding one of the plurality of pixel electrodes and a second capacitor electrode connected to a corresponding one of the plurality of storage capacitor lines;

    a first drive unit, connected to the plurality of storage capacitor lines, for selectively applying a storage capacitor potential to the plurality of storage capacitor lines; and

    a second drive unit, connected to the plurality of data lines, for alternately providing an image data signal having a positive polarity and an image data signal having a negative polarity to the plurality of data lines, wherein the second drive unit selects some of the data lines so that an equal number of image data signals having a positive polarity and image data signals having a negative polarity are provided to the selected data lines, the second drive unit simultaneously providing the selected data lines with the image data signals having a positive polarity and the image data signals having a negative polarity.
