ABSTRACT:
A novel compound usable as a component constituting liquid crystal materials having a positive dielectric anisotropy value and a liquid crystal composition containing the same are provided, which compound is an alcohol derivative expressed by the general formula ##STR1## wherein R.sup.1 represents a hydroxyalkyl group of 1 to 10 carbon atoms having hydroxyl group at the end or an intermediate position thereof; R.sup.2 represents an alkyl group or an alkoxy group each of 1 to 10 carbon atoms or --C.tbd.N; and ##STR2## represents ##STR3## and when R.sup.2 represents --C.tbd.N, ##STR4## represents ##STR5##
