In this report, the synchronized polymer stabilizing (SPS) method is applied to control molecular orientation in a cell of nematic liquid crystal. In the SPS method, UV light is irradiated and made to synchronize with an applied triangular wave voltage for an appropriate time duration. If UV light is irradiated in time durations in which the applied voltage takes a value in the vicinity of the maximum, the polymerization of monomers occurs in the vicinity of substrate surfaces because the ionizing initiators are more accumulated near the substrate surfaces. If the UV irradiation is limited in the duration of only one polarity of the applied voltage, the polymerization occurs in the vicinity of only one side of substrate surfaces. The pretilt angle obtained depends on the amplitude and frequency of the applied voltage.
