A phase transition-type liquid crystal composition.

摘要

A phase transition-type liquid crystal composition including a mixture of ester-type liquid crystal compound and chiral nematic liquid crystal compound having added thereto at least one of ethane-type liquid crystal compound and bicyclohexane-type liquid crystal compound. This liquid crystal composition exhibitis an extended with ( DELTA V) of voltage hysteresis and therefore a stabilized homoetropic (H min ) state, when its voltage hysteresis curve is plotted. The liquid crystal display devices or elements using this composition have a fast response characteristic and enable a large scale or area display and an input operation using keyboards.
