ABSTRACT:
A polymer surface in contact with a liquid crystal medium is exposed to polarized light, whereby a covalently bound anisotropic component of the polymer surface aligns in response to the polarized light. Alignment of the anisotropic component causes alignment of the liquid crystal medium. An interference pattern of two polarized lights causes the covalently bound anisotropic component to form microgrooves on the polymer surface. A liquid crystal cell includes at least one polymer surface that has a covalently bound anisotropic component that can align in response to polarized light and a liquid crystal in contact with the polymer surface.
