A liquid crystal medium having an optically isotropic liquid crystal phase is described, which has stability to heat, light and so on, a broad temperature range of liquid crystal phase, a large optical anisotropy and a large dielectric anisotropy. A liquid crystal composition is described, which includes an achiral component T and a chiral dopant and exhibits an optically isotropic liquid crystal phase. The achiral component T contains, as its first component, at least one compound selected from compounds represented by formula (1),
