Abstract

A liquid crystal display device including a polyimide alignment layer, having a bistable liquid crystal material and a polymer stabilizer in an amount effective to stabilize the liquid crystal, preferably about 2 weight percent, associated with the liquid crystal material, the liquid crystal having a low pretilt angle, to eliminate stripe tendency and to increase hysteresis. The device has a low driving voltage, low power consumption and fast switching.
