PROBLEM TO BE SOLVED: To ease or eliminate an effect of drive dispersion and to improve display quality by increasing a drive margin. SOLUTION: After a strobe pulse 3 for making an element an optional display state in a selection period is applied to a scan electrode of a ferroelectric liquid crystal display element, a TRIFLE(technique to reduce the long field latching effect) pulse 4 of the polarity opposite to the strobe pulse 3 is applied to the scan electrode, and a pause period (d) during which a scan voltage becomes 0 is provided between the applied period of the strobe pulse 3 and the applied period of the TRIFLE pulse 4. Thus, when the TRIFLE pulse 4 is applied to the scan electrode, the switching to a dark state is stabilized than the case that the pause period d is not provided, and the original effect of the TRIFLE pulse 4 is strengthened, and a non-rewrite margin is increased. Thus, the final drive margin being a common part between the non-rewrite margin and a rewrite margin is also increased necessarily.
