PCT No. PCT/JP96/01229 Sec. 371 Date Jan. 7, 1997 Sec. 102(e) Date Jan. 7, 1997 PCT Filed May 9, 1997 PCT Pub. No. WO96/35976 PCT Pub. Date Nov. 14, 1996The present invention relates to a driving method and system for an antiferroelectric liquid-crystal display device or, in particular, a gray-scale display method for realizing low cost without an increase in power consumption by controlling the state of an antiferroelectric liquid crystal frame by frame. According to the present invention, writing of pixels requires at least two scanning periods. Each scanning period is composed of a plurality of frames. Both frames during which the antiferroelectric liquid crystal assumes a first ferroelectric state and frames during which the antiferroelectric liquid crystal assumes a second ferroelectric state are not included in the same scanning period (FIG. 1).
