 horizontal scanning period has been divided into, and selecting a single scanning line adjacent to the previously selected scanning line during the subsequent horizontal scanning period and applying a selection voltage to the adjacent scanning line during the other of the two half periods of the horizontal scanning period; and a data line driver circuit for applying a turn-on or turn-off voltage to a pixel at a location corresponding to the scanning line selected the scanning line driver circuit via a corresponding data line such that the turn-on voltage is applied during a period with a length corresponding to a gray level in the period during which said selection voltage is applied and the turn-off voltage is applied during the remaining period. According to this
