    摘要: The invention relates to a liquid-crystalline medium essentially comprisinga) 5-65% by weight of a component A, comprising two or more compounds selected from group A: ##STR1## b) 20-95% by weight of a component B comprising two or more compounds selected from group B: ##STR2## and c) 0-40% by weight of a component C, comprising one or more compounds having a clearing point above 170.degree. C., where R, X and Y each, independently of one another, have the following meanings:R is in each case alkyl, oxaalkyl, haloalkyl or alkenyl having up to 7 carbon atoms,X is F, Cl, CHF.sub.2, CF.sub.3, OCHF.sub.2 or OCF.sub.3, andY is H, F or Cl.
