Abstract:
1. A liquid crystal display device, comprising: a display section; scanning signal lines in the display section; and data signal lines, the scanning signal lines being divided into groups each of which includes two or more of the scanning signal lines, the groups being sequentially selected so that (i) two or more of the scanning signal lines included in a selected one of the groups are sequentially scanned horizontally while (ii) each of the data signal lines is sequentially supplied with signal electric potentials having an identical polarity, the identical polarity of the signal electric potentials being reversed between sequentially selected ones of the groups, two or more dummy scanning periods being inserted between (a) a horizontal scanning period corresponding to a last horizontal scan in a former one of the sequentially selected ones of the groups and (b) another horizontal scanning period corresponding to a first horizontal scan in a latter one of the sequentially selected ones of the groups, at least one of the scanning signal lines, which is included in a group to be selected after the former one of the sequentially selected ones of the groups, being subjected to a dummy scan during the two or more dummy scanning periods so as to be in an active state for a predetermined period and then deactivated, the number of scanning signal line(s) to be in the active state during each dummy scanning period is the same as the number of scanning signal line(s) to be in the active state during each horizontal scanning period, each horizontal scanning period is equal in length to the dummy scanning period, and during each of the two or more dummy scanning periods, either (i) a different one of the scanning signal lines is subjected to the dummy scan, or (ii) only a same one of the scanning signal lines is subjected to the dummy scan.
