ABSTRACT:
A liquid crystal device including: a pair of substrates and a chiral smectic liquid crystal disposed between the pair of substrates. Each of the pair of substrates has an electrode for applying a voltage to the liquid crystal. The pair of substrates is provided with respective uniaxial alignment axes extending in directions which are parallel to each other or intersect each other at a prescribed angle. The chiral smectic liquid crystal is placed in such an alignment state that the liquid crystal assumes at least two stable states and provides a pretilt angle .alpha. (degrees), a tilt angle H (degrees), an inclination angle .delta. (degrees) of the liquid crystal layer, and an apparent tilt angle .theta.a satisfying the following relationships (I) and (II) in a temperature range of 10.degree.-55.degree. C.:
