Title: Cyclohexane derivatives, liquid-crystal composition, and liquid-crystal display element

Abstract: Novel liquid crystalline compounds which have a wide temperature range of liquid crystal phase, are excellent in miscibility with other liquid crystalline compounds, have a low viscosity, are low in toxicity, and are safe; liquid crystal compositions comprising the liquid crystalline compound; and liquid crystal display devices fabricated by using the composition are provided; and the compounds are cyclohexane derivatives expressed by the general formula (1) ##STR1## wherein R represents an alkylene chain having 2 to 10 carbon atoms in which alkylene chain ethylene group (--CH.sub.2 CH.sub.2 --) may be replaced by ethenylene group (--CH.dbd.CH--) or methylenoxy group (--OCH.sub.2 --); and M represents COOH or CN group.
