摘要：
A dicyclohexylethylene derivative is disclosed which has the formula, ##STR1## where R is a straight chain alkyl group of 1 to 8 carbon atoms, X is hydrogen or fluorine, m is 1 or 2, n is 0 or 1, and indicates that a substituent at the 1-position of the cyclohexane ring and a substituent at the 4-position thereof are at a trans configuration. A liquid crystal composition comprises at least one of the dicyclohexylethylene derivatives of the formula [I] above.
