PROBLEM TO BE SOLVED: To provide a liquid crystal display device using OCB(optically compensated birefringence) liquid crystal in which lowering of display brightness is suppressed and the occurrence of a reverse transition phenomenon is surely prevented. SOLUTION: A tendency for the reverse transition phenomenon to occur on a display picture is determined by detecting the maximum value of input image signals, i.e., the lowest potential applied on a liquid crystal panel and by taking a value derived from smoothing the detected value for a unit frame as a basis. When the reverse transition phenomenon is determined to tend to occur, for the purpose of enhancing effect on reverse transition depression of reverse transition preventing drive, for example a time interval for applying high potential is lengthened. When the reverse transition phenomenon is determined unlikely to occur, on the other hand, for example the time interval for applying high potential is shortened so as to weaken the effect on reverse transition depression.
