A novel method for liquid crystal alignment using in-situ exposure to linearly polarized ultra-violet (LPUV) light during imidization of polyimide has been devised. The alignment layers prepared by this method exhibit higher thermal stability than the conventional method that employs LPUV exposure after imidization. Multi-domain cells can be easily fabricated with the use of a photo mask and multi-step in-situ LPUV exposure during hard bake. With this method, it is also possible to generate pretilt angle using two-step LPUV exposure during imidization.
