摘要:
A liquid crystal composition comprising a silacyclohexane compound represented by the following formula (I): ##STR1## wherein R and R' denote an alkyl group, a mono- or di-fluoroalkyl group, an alkoxyalkyl group or an alkenyl group; at least one of ##STR2## denotes a silacyclohexylene group whose silicon at positions 1 or 4 has a substitutional group of H, F, Cl of CH.sub.3, and the other denotes a silacyclohexylene group whose silicon at positions 1 or 4 has a substitutional group of H, F, Cl or CH.sub.3 or a cyclohexylene group; and 0-2 of the substitutional groups X on the aromatic rings denote F and the remaining X's denote H.
