A sum of the number of frames constituting a scanning period and the number of frames constituting a pause period is an even number. A polarity of a POL signal in each frame in each of the scanning period and the pause period is reversed every frame. Further, the polarity of the POL signal is reversed at a timing when switching from the scanning period to the pause period is carried out, and is maintained at a timing when switching from the pause period to the scanning period is carried out. Alternatively, the polarity of the POL signal is maintained at a timing when switching from the scanning period to the pause period is carried out, and is reversed at a timing when switching from the pause period to the scanning period is carried out. |
