The present invention: (1) divides a selection period into a plurality of sub-selection periods (t11, t21, t31, t41), and distributes these sub-selection periods throughout the period in one frame; (2) further divides a sub-selection period into a plurality of divided sub-selection periods ((s1, s2), (s3, s4), (s5, s6), (s7, s8)), and switches electric potentials of the selection signals between divided sub-selection period in order to eliminate the effects of spikes in voltage from the scanning signals to be applied to adjacent scanning electrodes, and applies these features to commonly known multi-line driving method. The present invention is capable of: (1) controlling unevenness of display in the direction of signal electrodes (normally vertical direction), (2) not causing especially severe uneven display in the direction of signal electrodes and flickering even when the display contents change one after another, and (3) preventing the occurrence of an uneven display in the direction of scanning electrodes (normally horizontal direction).
