Liquid crystal device with chemically-induced high-tilt alignment coating |
| abstract |
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°) 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 α₁ (e.g., α₁ = 0° ; homogeneous alignment) with the surface and another of which alone would yield α₂ (e.g., α₂ = 90°, homeotropic alignment), but together they produce α₃ different from α₁ and α₂. |
