Electric power consumed in an operation of displaying a gray-scale image is reduced. One of a plurality of scanning lines is selected during one horizontal scanning period, and a selection voltage is applied to the scanning line during one of a first half period and a second half period that said horizontal scanning period has been divided into. When an intermediate gray level is displayed, the selection voltage is applied to a scanning line in an odd-numbered column during the second half period and the selection voltage is applied to a scanning line in an even-numbered column during the first half period. To a pixel at a location corresponding to the selected scanning line, a turn-on voltage and a turn-off voltage are applied via a corresponding data line during particular periods within the period during which the selection voltage is applied such that the turn-on voltage is applied during a period with a length corresponding to a gray level while the turn-off voltage is applied during the remaining period. Thus, when an intermediate gray level is displayed by a pixel, the voltage level of the data signal Xi applied to the pixel is switched as few times as twice per horizontal scanning period, and thus electric power consumed in switching the voltage level is suppressed.
