It is to manage both the reduction of
power consumption and the enhancement of quality of picture when a partial display operation is performed. A scanning line
driving circuit 350 supplies each of scanning lines 312 in a display region with selection signals in a second half part of one horizontal scanning time period and with non-selection signals in the rest thereof by inverting the polarity every vertical scanning time period. Further, the scanning line
driving circuit 350 supplies each of scanning lines 312 in a non-display region with non-selection signals by inverting the polarity every one or more vertical scanning time periods. A data line
driving circuit 250 supplies each of
data lines 212 with a
signal representing a positive-side
voltage level VDP and a
signal representing a negative-side
voltage level VDN in first and second half parts of a horizontal scanning time period, respectively, for a period of time of the same length in the case that a scanning line 312 in a display region is selected. Furthermore, the data line driving circuit 250 supplies each of
data lines 212 alternately with a
signal representing the positive-side
voltage level VDP and a signal representing the negative-side voltage level VDN every one or more horizontal scanning time period.
