1. A method of aligning a liquid crystal medium comprising exposing a polymer surface in contact with the liquid crystal medium to polarized light, said polymer surface having a covalently bound anisotropic component that aligns in response to the polarized light via photo-induced isomerization of the anisotropic component, thereby aligning the liquid crystal medium.
