Claim:
A liquid-crystalline medium having positive dielectric anisotropy, comprising one or more polymerizable compounds of formula I in which P 11 and P 12 are independently from one another a polymerizable group, Sp 11 and Sp 12 are independently from one another a spacer group having from one to 10 C-atoms or a single bond, X 11 and X 12 are independently from one another â€”Oâ€”, â€”Oâ€”COâ€”, â€”COâ€”Oâ€”, â€”Oâ€”COâ€”Oâ€” or a single bond, L are in each occurrence independently from each other H, F, Cl or alkyl with 1 to 5 C-atoms, r and s independently of one another are 0, 1, 2 or 3, and t is 0, 1 or 2, and one or more dielectrically positive compounds of formula II-2j in which R 2 denotes alkyl, alkoxy, fluorinated alkyl or fluorinated alkoxy having 1 to 7 C atoms, or alkenyl, alkenyloxy, alkoxyalkyl or fluorinated alkenyl having 2 to 7 C atoms, X 2 denotes halogen, halogenated alkyl or alkoxy having 1 to 3 C atoms or halogenated alkenyl or alkenyloxy having 2 or 3 C atoms, and L 21 to L 28 independently of one another, denote H or F, and one or more dielectrically positive compounds of formula III-1f-4 in which R 3 denotes alkyl, alkoxy, fluorinated alkyl or fluorinated alkoxy having 1 to 7 C atoms, or alkenyl, alkenyloxy, alkoxyalkyl or fluorinated alkenyl having 2 to 7 C atoms.
