Abstract
A method of tilting liquid crystal molecules is presented. The method entails providing a substrate including a photoalignment layer on top of a layer of liquid crystal molecules. The photoalignment layer is exposed to patterned light that is incident on the substrate at a substantially normal angle. The patterned light is polarized in a polarization direction that is non-parallel to an incident surface of the substrate.
