Claim Text:
1. A liquid crystal display apparatus comprising: a liquid crystal display unit; a video signal driving circuit; a scanning signal driving circuit; a common electrode potential controlling circuit; and a synchronizing circuit, wherein the liquid crystal display unit comprises: wherein the common electrode potential controlling circuit changes the potential of the common electrode into a pulse shape after the scanning signal driving circuit scans the entire scanning electrodes and transmits video signals to the pixel electrodes, the potentials of the video signals is determined by comparing the hold data of the individual pixels before the writing of the video signals, a variation in the potentials of the pixel electrodes associated with a variation in the potentials of the common electrodes to be changed into a pulse shape, the potentials of the storage capacitance electrodes to be changed into a pulse shape, or the potentials of both of them, and display data to be newly displayed, and, the comparison of the data and the variation in the potentials is made by using look up tables (LUTs) prepared in advance, said LUTs differing from one another according to the polarity of the video signals.
