【Abstract】 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.更多还原
