Patent ID: 8551358

Claim:
A liquid-crystalline medium, comprising a polymerizable component (A) containing one more polymerizable compounds and a liquid-crystalline component (B) containing one more compounds of formula I in which R 0 is an alkyl or alkenyl radical having from 1 to 15 carbon atoms which is unsubstituted, monosubstituted by CN or CF 3 , or at least monosubstituted by halogen, in which one or more CH 2 groups are optionally, independently of one another, replaced by —O—, —S—, —CO—, —CO—O—, —O—CO—, —O—CO—O—, —CH═CH— or —C≡C— in such a way that O atoms are not linked directly to one another, are each independently Y 1 and Y 2 are each, independently of one another, H or F, Z 1 is —CF 2 O—, —OCF 2 — or —COO—, Z 2 is —O—, —S—, —CO—, —COO—, —OCO—, —S—CO—, —CO—S—, —OCH 2 —, —CH 2 O—, —SCH 2 —, —CH 2 S—, —CF 2 O—, —OCF 2 —, —CF 2 S—, —SCF 2 —, —CH 2 CH 2 —, —CF 2 CH 2 —, —CH 2 CF 2 —, —CF 2 CF 2 —, —CH═CH—, —CF═CH—, —CH═CF—, —CF═CF—, —C≡C— or a single bond, X 0 is F, Cl, halogenated alkyl, halogenated alkenyl, halogenated alkoxy, or halogenated alkenyloxy having up to 6 carbon atoms, and r is 0, 1, 2 or 3, which liquid-crystalline medium has a positive dielectric anisotropy Δ∈.
