Layer rotation in antiferroelectric liquid crystal cells with rubbed pclymer film has been studied. According to the microscopic observation under the external field of various waveforms, we found that the direction of layer rotation was positive when τd+τd-, and vice versa, where τd+ and τd- indicate the response time from the positive ferroelectric(F) state to the antiferroelectric(AF) state and that from the negative F state to the AF state, respectively. The layer rotation angle was in proportion to the difference between τd- and τd^-.
