Abstract:
A liquid crystal medium is described, having a wide temperature range of a liquid crystal phase, a large optical anisotropy and a large dielectric anisotropy, and exhibiting an optically isotropic liquid crystal phase. The liquid crystal medium features including a chiral dopant and a liquid crystal compound with chloronaphthalene ring and exhibiting an optically isotropic liquid crystal phase.
