Claim Text:
1. A liquid crystal mixture comprising a compound of formula (I) wherein R R a) F, b) a linear or branched alkyl group of 1 to 20 C atoms, or a linear or branched alkenyl group of 2 to 20 C atoms, wherein in either case one or two —CH c) a radical wherein independently from the respective meanings in (I) R M A is i) —C(═Y)—, wherein Y is CH—Z, wherein Z is phenylen-1,4-diyl, optionally substituted by one to three halogen atoms, alkyl or alkyloxy groups of 1 to 4 C atoms, with the proviso that M ii) —CHY—, wherein Y is CH iii) wherein p and q are 0, 1 or 2, wherein the sum of p+q is 1; M are, independently from another, phenylen-1,4-diyl, which is optionally substituted by one, two or three F, or cyclohexan-1,4-diyl, which is optionally substituted by one CN, CH X is H, OH, a linear or branched alkyl or alkyloxy group of 1 to 20 C atoms, wherein one or two —CH m is 0 or 1; or X and M a) a ring of 4 to 16 members, optionally substituted by an alkyl radical of 1 to 15 C atoms, b) a combination of two either directly linked or spiro-linked rings of, independently from another, 4 to 16 members, optionally substituted by an alkyl radical of 1 to 15 C atoms, wherein the rings, independently from another, are carbocycles or carbocycles comprising B, N, O or S heteroatoms.
