负性向列相液晶ＭＢＢＡ在作为液晶的取向层的花生酸Ｌ－Ｂ膜上取得了较好的垂直取向排列效果。通过偏光显微镜利用锥光干涉效应研究了负性向列相液晶ＭＢＢＡ在花生酸Ｌ－Ｂ膜上的取向排列，发现在加电压后液晶受电场作用偏转具有确定的择优取向，芥方向沿Ｌ－Ｂ膜的生长方向。同时对液晶盒的电光特性进行了测量，显示了典型的电控双折射形电光特性曲线。它也肯定了择忧倾斜取向的存在。
The negative nematic liquid crystal MBBA has a better vertical alignment effect on the arachidic L-B film which is the alignment layer of the liquid crystal. The alignment of the negative nematic liquid crystal MBBA on the arachidic L-B film was investigated by using a cone-beam interference effect with a polarizing microscope. It was found that there was a definite preferred orientation of the liquid crystal under the action of electric field. Membrane growth direction. At the same time, the electro-optic characteristics of the liquid crystal cell were measured and the typical electro-optic birefringence electro-optic characteristic curve was shown. It also affirmed the existence of choice and inclination.
