<p>Of a display screen, only a pixel corresponding to an intersection between a specific scanning line and a specific data line is used as a display area. In order to suppress the power consumption to a low level, for the specific scanning line, one scanning line is selected every horizontal scanning period, and a selection voltage is applied to the selected scanning line for one of the halves of one horizontal scanning period. Moreover, the polarity of the selection voltage is inverted at least every two or more horizontal scanning periods. The nonselection voltage is inverted in polarity every one or more vertical scanning periods and fed to the scanning line other than the specific one. For the period for which the specific scanning line is selected, moreover, a non-on voltage for the data line other than the specific one is inverted in polarity in accordance with the polarity of the selection voltage applied to the selected scanning line every two or more horizontal scanning periods corresponding to the period of the polarity inversion of the selection voltage.</p> |
