Abstract
A liquid crystal medium having stability to heat, light and so forth, a wide temperature range of a liquid crystal phase, a large refractive index anisotropy and a large dielectric anisotropy and an optically isotropic liquid crystal phase is described. A liquid crystal composition is characterized by exhibiting the optically isotropic liquid crystal phase and containing achiral component T containing at least one compound selected from the group of compounds represented by formula (1) as a first component, and a chiral agent: wherein, for example, Ris alkyl having 1 to 20 carbons, L, L, L, L, Land Lare independently hydrogen or fluorine, and Xis halogen.
