The invention relates to a ferroelectric liquid-crystalline medium having improved low-temperature behavior, pronounced bistability and a phase sequence containing the phases isotropic, cholesteric, smectic A and chiral smectic C, comprising an achiral base material having a broad smectic C phase and at least one chiral dope which induces a spontaneous polarization of from 5 to 40 nCcm.sup.-2 in the achiral base material, characterized in that the medium has a chiral smectic C phase which is stable at least to -30.degree. C., and to the use thereof in electro-optical devices.
