| Abstract: | Chemical property of the UV light photo-polymer material VP. was studied in thispaper. The NMR spectrum of the photo-alignment material was measured. Thecharacteristics aligning LC-6710A liquid crystal molecules of this photo-alignment materialwas also investigated by polarized light microscope photography. The micrography of thephoto-alignment surface before and after the UV light photopolymerization was observedby atomic force microscope (AFM). The produced pretilt angle of liquid crystal by thephoto-alignment substrate was measured. The electro-optical and time response propertiescurves of twisted nematic liquid crystal display (TN-LCD) cell with single side photoalignment agent was obtained. The mechanism of liquid crystal molecule alignment onsubstrate surface was discussed. |
