Abstract
High-tilt (e.g., 5.degree.-85.degree.) can be achieved by chemical treatment of the interior surfaces of a liquid crystal device. Illustratively, the treatment entails applying a combination of surface coupling agents one of which alone would cause the LC director to make and angle .alpha..sub.1 (e.g., .alpha..sub.1 =0.degree.; homogeneous alignment) with the surface and another of which alone would yield .alpha..sub.2 (e.g., .alpha..sub.2 =90.degree., homeotropic alignment), but together they produce .alpha..sub.3 different from .alpha..sub.1 and .alpha..sub.2.
