The present invention provides a liquid crystal medium having an optically isotropic liquid crystal phase having stability against heat, light, etc., a wide liquid crystal phase temperature range, a large refractive index anisotropy, a large dielectric anisotropy and the like. 1. A liquid crystal composition containing an achiral component T containing at least one compound selected from the group of compounds represented by the formula (1) and a chiral agent as a first component and expressing an optically isotropic liquid crystal phase. Wherein, R 1 is, for example, a C 1 -C 20 alkyl, L 1, L 2, L 3, L 4, L 5 and L 6 are independently hydrogen or fluorine, X 1 is, e.g. , Halogen. |
