PCT No. PCT/JP85/00508 Sec. 371 Date May 12, 1986 Sec. 102(e) Date May 12, 1986 PCT Filed Sep. 12, 1985 PCT Pub. No. WO86/01926 PCT Pub. Date Mar. 27, 1986.According to the present invention, in a liquid crystal display apparatus, there are provided second horizontal switching elements MBl to MBm, which are driven at the advanced phase relative to picture element switching signals phi Hl to phi Hm, at columns Ll to Lm to which a video signal is supplied, a signal, which is derived through said second horizontal switching elements MBl to MBm, is fed back through an inverting circuit (14) and the like to an input terminal (1), and there are provided third switching elements MRl to MRm which are turned on at every predetermined period. According to this apparatus, since a signal derived from a liquid crystal cell C is returned to the same liquid crystal cell C, the displacement of the picture and the like can be avoided, any special scanning and the like are not required and a prior art driving circuit and so on can be used as they are. Further, since the potential of the signal line is reset at every predetermined period, it is possible to prevent the quality of the picture from being deteriorated by a residual charge and the like and the excellent display of a still picture can be carried out over a long time period.
