摘要：
A nematic liquid crystal composition whose threshold voltage is scarcely influenced by temperature changes is provided, which composition comprises at least two components at least one of which is a compound expressed by the formula ##STR1## wherein R.sub.1 represents an alkyl group or an alkoxy group each of 1 to 10 carbon atoms, ##STR2## each independently represent a benzene ring or a cyclohexane ring and n represents an integer of 0 or 1, said compound being contained in 10 to 100% by weight in said composition.
