Abstract
A liquid crystal display device includes a pair of substrates, on at least one of which pixels or scanning lines and switching elements for selecting desired pixels or scanning lines are arranged, a liquid crystal material sandwiched between the substrates, a driving means for driving a pixel group arrayed on each of selected scanning lines with the same polarity, and a polarity reversal means for compensating for flickers by reversing the polarity. In the display area, the scanning line selection order is arbitrarily determined, and the polarities are reversed on the basis of the determination result so as not to produce a bundle of scanning lines having the same polarity within one field.
