中文摘要：

研究挠曲电效应对向列相液晶盒电光效应的影响.通过变分理论得到液晶指向矢满足的微分方程和边界条件,利用差分迭代的方法计算强锚定和弱锚定液晶盒中液晶指向矢的分布情况.借助琼斯矩阵的方法,计算两种液晶盒电光特性曲线.此外,在计算中同时考虑了挠曲电表面和体积效应.

英文摘要：

Flexoelectric effect on electro-optical characteristics of a nematic liquid crystal cell is investigated. Differential equations and boundary conditions for director of liquid crystal are obtained with variation theory. Distributions of director of nematic liquid crystal （NLC） cells with strong anchoring and weak anchoring are calculated by a finite-difference iterative method. With Jones matrix method, transmittancevoltage characteristics of liquid crystal cells are obtained. Surface flexoelectric effect and bulk flexoelectric effect are considered.
