銆�銆�Abstract: The field induced stereo regular polymerization of polymer dispersed nematic liquid crystal both positive and negative dielectric character are experimental studied, the picture in kind and polarizing microscope photograph of samples are given. The experiment results show that there are obvious distinguish with in different area of electric field applied or not, the electric field have the induced stereo regular polymerization action under the polymer dispersed liquid crystal sample preparation process. The experiment results are useful to understand the influence of polymer border condition to liquid crystal micro drop configuration, and are in a sense of gain a good deal of to design a new type liquid crystal display device.
