为实现液晶显示器件的各种电光效应,液晶分子在电极表面必须有一定的取向,垂直排列和水平排列是二种常用的高度定向排列。本文首先扼要地小结这个领域里的技术现状,然后介绍我们的工作情况。一、垂直排列模式的电极表面处理 Friedel首先为这二种排列状态作了很有意义的讨论,自此以后,许多人论述了得到定向排列的方法,这些方法如表1及表6所示。 In order to realize the various electro-optical effects of the liquid crystal display device, the liquid crystal molecules must have a certain orientation on the electrode surface. The vertical arrangement and the horizontal arrangement are two commonly used highly oriented arrangements. This article starts with a brief summary of the state of the art in this area, and then introduces our work. First, the vertical arrangement of the electrode surface treatment Friedel first of these two arrangements made a very meaningful discussion, and since then, many people discussed the method of orientation, these methods are shown in Table 1 and Table 6.
