We have investigated the alignment of liquid crystal LC-6710A molecules with Cinnamate material 2-(cinnamoyloxy) ethyl methacrylate (CEMC). The change of alignment of substrate surface was observed before and after photochemical reaction. The pretilt angle of LC molecules in photo-alignment cell was measured. The electro-optical property and time response curves of twisted nematic liquid crystal display (TNLCD) with single side photo-alignment substrate were obtained. The process of photochemical reaction of the material CEMC using linear polarized photopolymerization method by UV-light was studied in this paper. The mechanism of liquid crystal molecules alignment on substrate surface was discussed.
