ABSTRACT:
A liquid crystal (composition) containing a ferroelectric liquid crystal shows a layer inclination angle .delta. in smectic phase providing a specific temperature dependence. The inclination angle .delta. increases on temperature decrease down to a mediate temperature and decreases on temperature decrease below the mediate temperature. The inclination angle .delta. keeps a positive value in an ambient temperature or starts to increase again on further temperature decrease before it reaches zero degrees. The liquid crystal (composition) is usable for providing a liquid crystal device or apparatus with decreased temperature dependences of driving conditions and improved low-temperature storage properties.
