Abstract
A liquid crystal compound represented by the following general formula (1): ##STR1## wherein R is a linear alkyl group having 6 to 12 carbon atoms, X and Y are both a hydrogen atom, or one of them is a hydrogen atom and the other is a fluorine atom, m is an integer of 0 to 5, n is an integer of 1 to 5, and C* is an asymmetric carbon atom. Since the liquid crystal compounds of the present invention have an anti-ferroelectric phase or a ferrielectric phase and the anti-ferroelectric phase or a ferrielectric phase has a highly practical phase sequence and wide temperature range, they are of great industrial value.
