Provided are an anti-ferroelectric liquid crystal composition consisting essentially of (a) a swallow-tailed compound of the formula (1), (b) an anti-ferroelectric liquid crystal compound of the formula (2), and (c) a phenyl ester compound of the formula (3), and a liquid crystal display device using the composition. The above anti-ferroelectric liquid crystal composition has an anti-ferroelectric phase in a broad temperature range, has a high response time I in the transition from an anti-ferroelectric state to a ferroelectric state and a proper response time II in the transition from a ferroelectric state to an anti-ferroelectric state, and can therefore provide an anti-ferroelectric liquid crystal display device having high display quality.
