    摘要: A liquid crystal device is constituted by a pair of substrates each having thereon an electrode and a uniaxial alignment film, and a chiral smectic liquid crystal disposed between the substrates. At least one of the uniaxial alignment films is a film comprising an electroconductive polymer doped with at least two species of dopants, which preferably include a first type dopant capable of dedoping into the liquid crystal due to electric field application or diffusion, and a second type dopant substantially incapable of dedoping into the liquid crystal. The resultant liquid crystal device is alleviated with respect to voltage hysteresis and is suitable for gradational display.
