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 the liquid crystal preferably having a low or medium pretilt angle to eliminate undesired states and stripe tendency and to increase hysteresis. The device has a low driving voltage, low power consumption and fast switching.
