ABSTRACT:
A liquid crystal device including a liquid crystal layer, orientation layers for orienting the liquid crystal layer, and adsorption layers provided in interfaces between the liquid crystal layer and the orientation layers and consisting of neutral and/or ionic molecules, and a method of manufacturing such a liquid crystal device make it possible to fill the trap level between the liquid crystal layer and the orientation layers to prevent an asymmetrical electric field from forming, thereby restraining hysteresis.
