<p>This invention relates to improved liquid crystal devices useful in liquid crystal displays as well as other devices such as optical shutters. The improvement resides in the use of high-tilt alignment coatings (e.g. 80 and 90) in the device. High-tilt (e.g., 5-85 DEG ) is achieved by chemical treatment of the interior surfaces of a liquid crystal device. Illustratively, the treatment entails applying a combination of surface coupling silane agents one of which alone would cause the LC director to make and angle alpha 1 (e.g., alpha 1 = 0 DEG ; homogeneous alignment) with the surface and another of which alone would yield alpha 2 (e.g., alpha 2 = 90 DEG , homeotropic alignment), but together they produce alpha 3 different from alpha 1 and alpha 2.</p> |
