Abstract
We demonstrate a plasma-beam-processed polyimide (PI) surface to effectively align liquid crystal (LC) molecules. The pretilt angles of LCs can be varied between 0 and 3.5°, and the PI surface energy can be adjusted by controlling the plasma beam with an energy of 450 eV at an incident angle varying from 0 to 80° with respect to the normal direction of the substrate. Additionally, a method was developed to quickly evaluate the level of anchoring force of LC when compared with a rubbed-aligned LC cell. The performance of this method should be under LC cells with the same alignment materials.
