There is provided a simple matrix liquid crystal panel in which the number of changes in waveform on a column electrode is suppressed without degrading a display quality even when the number of gray scales is increased, and a consumption power can be reduced. Pulse width modulation is performed with a sum total of a plurality of pulses selected in a plurality of frames, and the number of changes in column electrode for displaying a half tone pixel data on a pixel is set as 1 during the plurality of frames. Further, an occurrence order of dividing frames in an odd row is made different from that in an even row and interlaced scanning is conducted. Thus, the consumption power is greatly reduced as compared with the case of conventional pulse width modulation.
