摘要:
A liquid crystal display device of the present invention has a vertical scanning period in which the polarity of a display signal is positive and a vertical scanning period in which the polarity of a display signal is negative. When a pair of successive two vertical scanning periods is constituted by a first vertical scanning period and a second vertical scanning period, and when a target gradation level to be displayed in the first vertical scanning period is GL1, and a target gradation level to be displayed in the second vertical scanning period immediately after the first vertical scanning period is GL2, GL1 and GL2 being integers of 0 or more representing gradation levels, the liquid crystal display device includes a circuit (124) capable of supplying a display voltage corresponding to a gradation level to a pixel in the second vertical scanning period, the gradation level being expressed by GL2OD which satisfies a condition where |GL2OD-GL1| is larger than |GL2-GL1|, in the case where GL2 is different from GL1. The value of GL2OD when the polarity in the first vertical scanning period is positive and the polarity in the second vertical scanning period is negative is different from the value of GL2OD when the polarity in the first vertical scanning period is negative and the polarity in the second vertical scanning period is positive.
