Compensator with photochemically cured barrier layer and process

摘要

Disclosed is an optical compensator for a liquid crystal display comprising a transparent polymeric support, a photochemically cured barrier layer impermeable to the components of the support, an orientation layer, and a photochemically cured optically anisotropic layer, in order, wherein the photochemically cured barrier layer as disposed on the support has an indentation modulus of less than 2 GPa.
