Provided is a liquid-crystal composition that has a markedly reduced crystallization temperature relative to a mixture of homologs despite having a similar backbone structure, exhibits superb compatibility, and has negative dielectric-constant anisotropy (Delta[epsilon]) of increased absolute value. A liquid-crystal composition containing two or more compounds that each have the same number of ring structures between two side chains, the number being between two and four inclusive, wherein at least one of the ring structures in each compound is a 2,3-difluorobenzene backbone, and among compounds in which each of the two side chains is linked to a different ring structure, the positions of the 2,3-difluorobenzene backbones differ. Letting N represent the number of ring structures, if the two chains have different molecular weights, the ring structures are numbered consecutively from 1 to N, with the position of the ring structure to which the side chain with the higher molecular weight is linked defined as 1 and the position of the ring structure to which the side chain with the lower molecular weight is linked defined as N; and if the two side chains have the same molecular weight, the positions of the ring structures to which the side chains are linked are defined as 1 and the positions of the ring structures to which no side chains are linked are defined as 2.
