PROBLEM TO BE SOLVED: To attain a small-sized and low-cost liquid crystal device using a liquid crystal panel with a memory effect. SOLUTION: A driving circuit 30 applies, to scanning electrodes of the liquid crystal panel 40 with the memory effect, a scanning voltage TPV composed of zero and a positive or negative unipolar voltage waveform, and also applies, to signal electrodes, a signal voltage SGV composed of zero and a unipolar voltage waveform having the same polarity as that of the scanning voltage. Further, image data is displayed at a pixel of the liquid crystal panel with the memory effect during a plurality of scanning periods, such that the polarities of the voltages applied between the scanning electrode and the signal electrode at a portion forming a pixel of the liquid crystal panel with the memory effect during a first scanning period and during a subsequent period of the plurality of periods are inverted.
