Disclosed herein is an optically active compound and a ferroelectric liquid crystal composition produced therefrom. The optically active compound has a fluorine atom introduced into the core nucleus so that it does not take on the smectic phase of a high order except for the smectic A phase and smectic C phase and which has carbonyl groups (for dipole) at adequate positions so that it exihibits greater spontaneous polarization. The ferroelectric liquid crystal composition is composed of a chiral component (including the optically active compound) and a non-chiral component, and hence it is superior in response performance.
