发明名称 LIQUID CRYSTAL DISPLAY PANEL AND PREPARATION THEREOF
摘要 PURPOSE: To provide a liquid crystal display panel which is remarkably improve in visual angle behavior. CONSTITUTION: A layer of a liquid crystal material is arranged in contact with the opposite surfaces of two alignment layers 21 and 22 adhered to transparent electrodes 16 and 17. The alignment layers are formed of substances which are able to give a pretilt angle to liquid crystal molecules 28. At least one alignment layer which is formed in only one alignment direction is selectively altered so as to a pretilt angle different from the pretilt angle generating capability of the unaltered area. The liquid crystal molecules having at least two different pretilt angles are provided, so when a voltage is applied between the electrodes, >=2 domains are generated. The pretilt angle generating capability in the altered area is varied by irradiation with an energy beam like ultraviolet rays. In an excellent example, a liquid material is a twist type nematic polymer.
