Abstract
Benzene derivatives useful as a component of liquid crystal compositions are provided which are expressed by the general formula ##STR1## wherein R represents a hydrogen atom or an alkyl group of 1 to 10 carbon atoms; R' represents a hydrogen atom, an alkyl group of 1 to 10 carbon atoms or an alkoxy group of 1 to 10 carbon atoms; and ##STR2## represents ##STR3## The derivatives exhibit small values of positive dielectric anisotropy; have broader liquid crystal temperature ranges; and in particular, have higher liquid crystalline-transparent points and yet have lower viscosities.
