Chiral phenols which induce a cholesteric phase in a nematic liquid crystal and simultaneously act as a stabilizer and are useful in electro-optical displays

摘要

Chiral phenols (I) induce a cholesteric phase in a nematic liquid crystal and simultaneously act as a stabilizer. Independent claims are also included for: (1) a liquid crystal medium (II) containing at least one chiral phenol (I); (2) electro-optical displays containing the medium (II); (3) a process for the production of a liquid crystal mixture by addition of a chiral phenol (I) and; (4) the resulting liquid crystal mixture.
