Abstract
A liquid crystal composition comprising (1) an achiral host mixture comprising (a) at least 20% by weight, based on the total weight of the host mixture, of a mixture of fluorinated phenylpyrimidine compounds capable of exhibiting an SmC phase, and (b) at least 10% by weight, based on the total weight of the host mixture, of at least one fluorinated terphenyl compound which enhances the phase sequence of said mixture, wherein the total amount of (a) and (b) is at least 50% by weight based on the total weight of the host mixture; and (2) at least one chiral dopant in an amount of not more than 10% by weight of the total weight of the composition.
