摘要： Disclosed is a polycyclic compound represented by the following formula (I):R.sup.1 --X.sup.1 --[A.sup.1 --X.sup.2 ]--[A.sup.2 --X.sup.3 ]--R.sup.2 (I)wherein R.sup.1 is a (halogenated) alkyl group of 6 to 16 carbon atoms, X.sup.1 is --O-- group or a single bond, A.sup.1 is a biphenylene group, a phenylene group or the like, A.sup.2 is 1-fluoro-3,4-dihydronaphthalene or the like, X.sup.2 and X.sup.3 are each --COO--, a single bond or the like, and R.sup.2 is an optically active group of 4 to 20 carbon atoms which has at least one asymmetric carbon atom. Also disclosed are a liquid crystal material consisting of the polycyclic compound, a liquid crystal composition comprising the liquid crystal material, and a liquid crystal element. This novel polycyclic compound is optically active and capable of being in a smectic phase in a wide temperature range including room temperature. The polycyclic compound can be used as a ferroelectric liquid crystal material or an antiferroelectric liquid crystal material. By the use of the liquid crystal material of the invention, a liquid crystal element having a quick response speed in a wide temperature range can be obtained.
