Claim Text:
1. A liquid crystal display device in which data signal lines, scanning signal lines, and pixels are formed in each of first and second regions installed in a display unit and in which a part of a current frame is written to the first region and the remainder of the current frame is written to the second region, wherein a data signal with polarity inverted for each vertical scanning period or every plurality of vertical scanning periods is supplied to each data signal line, a scanning direction in the first region is identical to a scanning direction in the second region and the first and second regions are arranged to line up in this order in the scanning direction, and at least in the first region, a potential of the data signal supplied to each data signal line is corrected according to a distance from a pixel corresponding to the scanning signal line scanned in the first horizontal scanning period, when n (where n is an integer equal to or greater than 1) scanning signal lines are installed in the first region and Vsl is assumed to be the potential of the data signal corresponding to a video signal input from an outside, a corrected potential Vsl′(k) (where k is an integer equal to or greater than 1 or equal to and less than n) of the data signal supplied to each data signal line of the first region for a k-th horizontal scanning period is expressed as in:
