    摘要: A nematic liquid crytalline compound selected from the group consisting of compounds represented by the general formula ##STR1## compounds represented by the general formula ##STR2## compounds represented by the general formula ##STR3## and compounds represented by the general formula ##STR4## wherein R and R', independently from each other, represent a linear alkyl group having 1 to 7 carbon atoms, and each cyclohexane ring is arranged in a trans(equatorial-equatorial) form. These compounds have higher nematic phaseisotropic liquid phase transition temperatures than conventional liquid crystalline compounds.
