An antiferroelectric composition comprising 70 wt % or more of a mixture consisting of two groups of compounds represented by the following general formula (I): wherein each of R, R1, R2 and R3 are an atom or an atomic group, R is an atomic group having the most carbon atoms, C* represents an asymmetric carbon, R1, R2, and R3 are numbered in order of increasing number of carbon atoms (i.e. R1<R2<R3), or, if two or more groups have the same number of carbon atoms, they are numbered in order of increasing atomic group weight or increasing atomic weight, and wherein one component of the mixture has R1, R2 and R3 arranged clockwise when the molecule is viewed along the R-C bond, with the C* atom in front, and the other, counterclockwise. The composition provides an antiferroelectric liquid crystal composition having a lower crystal temperature and a wide liquid crystal temperature range with a small number of component compounds.
