摘　　要：液晶作为一种最有前途的平板显示材料,其分子在液晶盒内的排列特性对显示器件的设计及制作无疑是极为重要的.本文提出了一种新的研究分子排列特性的光波导方法——全反射光波导方法.将这种新方法与半泄漏波导方法进行了比较.通过计算机模拟,发现新方法对液晶指向矢的扭曲角、倾斜角及一些局域的畸变层更为敏感,非常适用于分析指向矢排列山较复杂的液晶盒样品.本文介绍了全反射光波导方法的基本原理、实验方法及其在研究液晶的排列特性上的应用.Being a flat display material, Liquid crystal has immense premise. It’s molecular aligning properties in a liquid crystal cell are undoubtedly very important for the designing and making a display device. A new optical guided method named as the total reflection guided modes method which is used to study molecular alimning properties is present in this paper. The comparison was made between the half leaky guided modes method and the new technique. The simulation showed that the new method is more sensitive to the twist angle, tilt angle and some special cases than the previous method, it’s very suitable to be used to study complex samples of liquid crystal cell. In this paper, the fundamental principle and the experiment method of the total reflection guided modes method and it’s application in the analysis the aligning properties of the liquid crystal are introduced.
