A silacyclohexane compound represented by the following general formula (I). ##STR1## In this formula, R denotes a linear-chain alkyl group with a carbon number of 1-10, a fluoroalkyl group with a carbon number of 1-10 in which a fluorine atom(s) is substituted for one or two hydrogen atoms, an alkoxy group, a branched-chain alkyl group with a carbon number of 3-8, an alkoxyalkyl group with a carbon number of 2-7, or an alkenyl group with a carbon number of 2-8. a and b denote 0 or 1 and (a+b)=0 or 1; For ##STR2## at least one of the two denotes a trans-1-sila-1,4-cyclohexylene or a trans-4-sila-1,4-cyclohexylene group whose silicon at position 1 or position 4 has a substitutional group(s) of H, F, Cl or CH.sub.3. X denotes H, CN, F, Cl, CF.sub.3, CF.sub.2 Cl, CHFCl, OCF.sub.3, OCF.sub.2 Cl, OCHFCl, OCHF.sub.2, R or OR. Y and Z denote F, Cl or CH.sub.3. i and j denotes 0, 1 or 2.
