A liquid crystal compound exhibiting a positive dielectric anisotropy has a formula: R-X-CH2O-Ar-CN where R is an alkyl or alkoxy group, X is a 1,4-disubstituted bicyclo(2.2.2)octane ring or a 1,4- disubstituted benzene ring, Ar is a 1,4- disubstituted benzene ring, or a 4,4'- disubstituted biphenyl ring or a 2,6- disubstituted naphthalene ring, and CN is a cyano group, provided that where R is an alkoxy group X is a 1,4- disubstituted benzene ring. |
