Paper Abstract

We found that the monomers with vinyl groups at two ends of the main chain after exposed to linearly polarized UV light can induce homogeneous alignment of liquid crystal molecules. The monomer films were coated on the surface of indium tin oxide glass substrates and then direclty illuminated by LPUV. UV-visible spectra elucidated high photochemical reaction degree obviously. The petilt angle of liquid crystal was 0.8 degree. Good electro-optic characteristics of TN-LCDs were obtained and multi-domain mode was fabricated using these photo-alignment materials.
