摘要：
A racemic compound of the formula (1)
and an anti-ferroelectric liquid crystal composition consisting essentially of said racemic compound and one anti-ferroelectric liquid crystal compound of the formula (2) or a mixture of two or more compounds selected from anti-ferroelectric liquid crystal compounds of the formula (2),
said composition having excellent steepness of threshold, having an anti-ferroelectric phase over a broad temperature range and having the performance of a high response speed and a high contrast.
