摘要： A liquid crystalline compound having a remarkably high .DELTA.n and good miscibility with other liquid crystalline compounds, and expressed by the general formula (1) ##STR1## wherein R.sub.1 represents, for example, a halogen atom, cyano group, or an alkyl or alkenyl group of 1 to 15 carbon atoms in which alkyl or alkenyl group hydrogen atom may be replaced, for example, by fluorine atom, and one or not-adjacent two or more methylene groups may be replaced by oxygen atom, --CH.dbd.CH-- or --C.tbd.C--; R.sub.2 represents an alkyl group of 1 to 10 carbon atoms or hydrogen atom; rings A.sub.1, A.sub.2, A.sub.3, and A.sub.4 independently represent, for example, 1,4-cyclohexylene or 1,4-phenylene in which hydrogen atom may be replaced by a halogen atom or cyano group; Z.sub.1, Z.sub.2, and Z.sub.3 independently represent, for example, a covalent bond or --CH.sub.2 CH.sub.2 --; s and t are 0 or 1; u is an integer of 1 to 5; and each of the elements in the general formula may be its isotope. A liquid crystal composition and a liquid crystal display device using the compound are also disclosed.
