摘要：
Novel anti-ferroelectric liquid crystal compounds of the formula (1), ##STR1## wherein R is a linear alkyl group having 6 to 12 carbon atoms, X is a hydrogen atom or a fluorine atom, n is an integer of 2 to 7, p is an integer of 0 to 2 and C* is an asymmetric carbon atom. The above anti-ferroelectric liquid crystal compounds have an anti-ferroelectric phase in a broad temperature range and have a low melting point, so that they can be advantageously used as a main component for a practically valuable liquid crystal material or as a component for a liquid crystal composition.
