Abstract
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), wherein Ris Calkyl, the rings Ato Aare 1,4-phenylene, Zto Zare single bonds, Yand Yare fluorine; Xis halogen, and i, j, k, m, n, p and q are independently 0 or 1.
