Liquid crystalline medium and liquid crystal display

A liquid crystal medium, comprising:

• a dielectrically neutral component, component A, comprising a dielectrically neutral compound of formula I
• a dielectrically positive component, component B, comprising one or more dielectrically positive compounds having a dielectric anisotropy of more than 3, which includes one or more compounds selected from the group of compounds of formulae II-1a to II-1e:
• wherein
• R2 is alkyl, alkoxy, fluorinated alkyl or fluorinated alkoxy with 1 to 7 C-atoms, or alkenyl, alkenyloxy, alkoxyalkyl or fluorinated alkenyl with 2 to 7 C-atoms,
• L21 to L24, are, independently of each other, H or F, and
• X2 is halogen, halogenated alkyl or halogenated alkoxy with 1 to 3 C-atoms or halogenated alkenyl or halogenated alkenyloxy with 2 or 3 C-atoms;
• and;
• one or more compounds of formula VI:
• wherein
• R61 and R62, are, independently of each other, alkyl, alkoxy, fluorinated alkyl or fluorinated alkoxy with 1 to 7 C-atoms, or alkenyl, alkenyloxy, alkoxyalkyl or fluorinated alkenyl with 2 to 7 C-atoms,
• and in case it is occurring twice in each occurrence independently of each other, is
• Z61 and Z62 are, independently of each other, and in case Z61 is present twice, also these independently of each other, —CH2CH2—, —COO—, trans- —CH═CH—, trans- —CF═CF—, —CH2O—, —CF2O— or a single bond, and
• r is 0, 1 or 2;
• wherein the concentration of the component A in the medium is from 30% to 65% by weight of the total medium.
