ABSTRACT:
Small-pitch cholesteric liquid crystal mixtures are temperature compensated. They are particularly useful when no, or only a slight, temperature dependence of the selective reflection is permissible, because a considerable temperature dependence would interfere with or render wanted effects impossible. They are composed of a nematic liquid crystal doped with at least two chiral additives satisfying the following conditions:
