【発明の名称】正の誘電体異方性液晶及び著しく傾斜した非垂直表面配列を伴う光バルブと、それに関する操作方法
Document Type and Number:
Japanese Patent JP2792700
Kind Code:
B2
Abstract:
A liquid crystal cell useful in light valves is disclosed in which positive anisotropy liquid crystals are installed at an initial off-perpendicular alignment within the approximate range of 6 DEG -45 DEG . A light valve employing the cell is initially biased to a voltage approximately corresponding to a transmissivity peak; the selection of the exact bias voltage involves a trade-off between contrast and response speed. The cell surfaces are characterized by generally flat macrostructures and tilted surface microstructures, with an overcoat on the surfaces of a long chain alcohol with alkoxy groups derived therefrom bonded to the tilted surface microstructure. The alcohol molecules have the formula ROH, where R is a carbon chain having at least six carbon atoms therein.
