Liquid crystal medium

A liquid-crystalline medium comprising a mixture of polar compounds having positive dielectric anisotropy, comprising at least one compound of the formula I in a total concentration of ≥40%,

• from 6% to 13% of at least one compound of formula IV-8 or IV-11
• and
• at least one compound of formula IB
• in which
• R1 denotes an alkyl or alkoxy radical having 1 to 15 C atoms, where one or more H atoms in these radicals may be replaced by F and, in addition, one or more CH2 groups may each be replaced, independently of one another, by
• —C≡C—, —CH═CH—, —O—, —CO—O— or —O—CO— in such a way that O atoms are not linked directly to one another,
• on each occurrence, identically or differently, denote
• L11 and L12, independently of one another, denote H or F,
• X1 denotes F, Cl, CN, a halogenated alkyl radical, a halogenated alkenyl radical, a halogenated alkoxy radical or a halogenated alkenyloxy radical having up to 6 C atoms
• R41 and R42, independently of one another, denote n-alkyl having 1 to 7 C atoms,
• wherein the clearing temperature of said liquid-crystalline medium is at least 120° C.
