Supertwisted liquid crystal displays in which the nematic liquid crystal mixture contains at least one component of group A, consisting of the compounds of formulas (AI) to (AVI), where R1 and R2 independently represent R, and R is alkyl with 1 to 12 C atoms, where also one or two non-adjacent CH2 groups can be replaced by -O-, -CH = CH-, -CO-, -O-CO- or -CO-O-, and up to four additional constituents, have very short response times. |
