ABSTRACT:
A liquid crystal showing a cholesteric phase at a higher temperature than the temperature giving a smectic phase is interposed between a pair of base plates to give a liquid crystal device. At least one of the base plates has a face to which an orientation controlling function is imparted for preferentially orienting the liquid crystal molecules in contact with the face in one direction.
