Abstract
A compound represented by the following general formula (I), a liquid crystal composition comprising the same, and a liquid crystal element using this liquid crystal composition. ##STR1## (wherein B.sub.1 and B.sub.2 represent independently a trans-1,4-cyclohexylene group or a 1,4-phenylene group wherein at least one hydrogen atom on the six-membered ring is optionally substituted by a halogen atom, Y represents a halogen-substituted alkyl group having 1 to 3 carbon atoms, a halogen-substituted alkoxy group having 1 to 3 carbon atoms, a cyano group, a fluorine atom or a chlorine atom, X represents a fluorine atom, a chlorine atom or a hydrogen atom, R.sub.1 represents an alkyl group having 1 to 10 carbon atoms or an alkoxy group having 1 to 10 carbon atoms, n and m represent independently 1 or 2 and p represents 0 or 1.) The compound of the present invention exhibits a large dielectric anisotropy, low threshold voltage, and favorable temperature-dependency of threshold voltage, as well as a favorable miscibility with a known liquid crystal compound, and therefore a liquid crystal composition comprising the compound can provide low voltage-operable liquid crystal display elements.
