Smectic liquid crystal mixture

A liquid-crystal mixture comprising A. at least one compound of the formula (I) in which R and R are identical or different and are a straight-chain or branched alkyl group having 1 to 18 or 3 to 18 carbon atoms respectively, where one CH2 group adjacent to the oxygen may also be replaced by -CO-, i...
