Liquid crystal medium with limited temperature-dependence of the d/p coefficient

摘要

The invention relates to a nematic liquid crystal medium of positive dielectric anisotropy containing one or more achiral liquid crystal compounds and a doping component, the doping component contains one or more doping substance which are chosen such that the medium, when used in a test cell suitable for determination of DELTA (d/p)(T), has a low temperature dependence of the d/p window d[ DELTA (d/p)]/dT.
