Abstract

A liquid crystal mixture applied in light modulating devices includes at least one compound selected from the group of compounds of formula I, at least one compound selected from the group of compounds of formula II and/or formula III, and at least one chiral compound. A light modulating device includes the liquid crystal mixture, where the light modulating device has reduced haze in the transparent state while increased opacity in the light scattering state.R-MG-X-MG-R  I
