Abstract:
1. A liquid-crystalline medium having positive dielectric anisotropy, comprising: one or more compounds of formula I and one or more compounds selected from formulas IA to IE in which X L R —C≡C—, —CF 2 O—, —OCF 2 — —OC—O— or —O—CO— in such a way that O atoms are not linked directly to one another, R —C≡C—, —CF 2 O—, —OCF 2 — —OC—O— or —O—CO— in such a way that O atoms are not linked directly to one another, A where the radicals a), b) and c) may be mono- or polysubstituted by halogen atoms, Z m denotes 0, 1 or 2, p denotes 1 or 2, q denotes 0 or 1, v denotes 1 to 6, and X wherein the amount of compounds of formulas IA, IB, IC, ID and IE in said medium is 2-30% by weight based on the total medium.
