Patent ID: 7646369

Claim:
A method of driving a liquid crystal display device comprising a plurality of scanning lines, a plurality of data lines arranged to intersect the plurality of scanning lines, a plurality of pixel electrodes arranged in correspondence with the intersections between the plurality of scanning lines and the plurality of data lines, a plurality of pixel switching elements for supplying the signals of the data lines to the pixel electrodes based on the signals of the scanning lines, and an opposed electrode facing the pixel electrodes, the method comprising: individually applying voltage to the plurality of scanning lines at separate timings to apply a selection potential and a non-selection potential to the pixel switching elements; inversion driving the opposed electrode between a first potential and a second potential; and setting at least one of the plurality of scanning lines to the selection potential at a common inversion timing when the opposed electrode is inverted from the first potential to the second potential, a scanning-line selection period that one of the plurality of scanning lines has the selection potential having a first selection period that an image signal is written to a first data line of the plurality of data lines, a second selection period that the image signal is written to a second data line of the plurality of data lines, a first non-selection period that the image signal is not written to all the plurality of data lines, and a second non-selection period that the image signal is not written to all the plurality of data lines, the common inversion period is in the first non-selection period, the first selection period is before the first non-selection period, the second selection period is after the first non-selection period, and the length of the first non-selection period is longer than that of the second non-selection period.
