Claim 10:
11. The LC medium according to claim 1, wherein the one or more polymerizable compounds are selected from the following formulae:, in which the individual radicals, on each occurrence identically or differently, and each, independently of one another, have the following meaning:
P1, P2, P3 a vinyloxy, acrylate, methacrylate, fluoroacrylate, chloro-acrylate, oxetane or epoxy group,
Sp1, Sp2, Sp3 a single bond or a spacer group where, in addition, one or more of the radicals P1-Sp1-, P2-Sp2- and P3-Sp3- may also denote Raa, with the proviso that at least one of the radicals P1-Sp1-, P2—Sp2 and P3—Sp3- present is different from Raa,
Raa H, F, Cl, CN, or straight-chain alkyl having 1 to 25 C atoms or branched alkyl having 3 to 25 C atoms, in which, in addition, one or more non-adjacent CH2 groups may each be replaced, independently of one another, by —C(R0)═C(R00)—, —C═C—, —N(R0)—, —O—, —S—, —CO—, —CO—O—, —O—CO—, or —O—CO—O— in such a way that O and/or S atoms are not linked directly to one another, and in which, in addition, one or more H atoms may each be replaced by F, Cl, CN or P1—Sp1-,
R0, R00 H or alkyl having 1 to 12 C atoms,
Ry and Rz H, F, CH3 or CF3,
X1, X2, X3 —CO—O—, —O—CO— or a single bond,

L F, Cl, CN, or straight-chain alkyl or alkoxy having 1 to 12 C atoms, or branched alkyl or alkoxy having 3 to 12 C atoms, straight chain alkenyl, alkynyl, alkylcarbonyl, alkoxycarbonyl, alkylcarbonyloxy or alkoxycarbonyloxy having 2 to 12 C atoms, or branched alkenyl, alkynyl, alkylcarbonyl, alkoxycarbonyl, alkylcarbonyloxy or alkoxycarbonyloxy having 4 to 12 C atoms, in each case optionally mono- or polyfluorinated,
L′, L″ H, F or Cl,
