To provide the driving method for a liquid crystal display panel and its control method which can reduce display defects at the time of switching from a non-display operation period to a display operation period.

This method drives a liquid crystal display panel, equipped with a means which displays one screen of the liquid crystal display panel 1 by displaying a desired pattern several times by applying a voltage sequentially to pixel electrodes provided on the liquid crystal display panel, a means which controls the operation for applying the voltage to the pixel electrodes, and a means for generating the voltage, so that a non-display operation period wherein the desired pattern is not displayed is present in one frame wherein one screen of the liquid crystal display panel is displayed. At this time, the operation for applying the voltage to the pixel electrodes is performed even in the non-display operation period.
