Disclosed is a liquid crystal medium for an MLC, TN or STN display that preferably has a very high specific resistance and a low threshold voltage. A liquid crystal medium based on a mixture of polar compounds having a positive dielectric anisotropy comprising the formula I Wherein R is H, a substituted or unsubstituted alkyl or alkenyl group having up to 18 carbon atoms, ring A is X is CN or QY (where Y is H, F or Cl, Q is a chain divalent bond or a single bond having a carbon atom), m is 0 or 1, and n is 0, 1 or 2], which is one or more fluorophenylcyclohexene derivatives.
