Thermally Stable LC Alignment on Polyimide Films Exposed to UV During Imidization
SID Symposium Digest of Technical Papers
Polyimide alignment layers have been prepared using “in-situ” exposure to linearly polarized UV LPUV light during imidization. Liquid crystal alignment on these layers exhibits higher anchoring strength and thermal stability than the “conventional” UV method that employs LPUV exposure after imidization. The in-situ method requires fewer steps and shorter processing time compared to the conventional method.
