液晶取向问题是液晶器件中的最关键问题.定量分析了摩擦取向处理后,取向膜表面的液晶分子取向度,用红外二向色性吸收实验证实了取向膜表面的液晶分子取向度是液晶体内部的1/3～1/2.
The liquid crystal alignment problem is the most critical issue in liquid crystal devices.A quantitative analysis of the orientation degree of the liquid crystal molecules on the alignment film surface after the rubbing alignment treatment confirms that the liquid crystal molecular orientation on the alignment film surface is liquid crystal Internal 1/3 ~ 1/2.
