Abstract:
1. A liquid crystal composition exhibiting an optically isotropic liquid crystal phase, the liquid crystal composition comprising an achiral component T and a chiral dopant, wherein the achiral component T contains, as a first component thereof, at least one compound selected from the group consisting of compounds represented by formula (1) in an amount of 32 wt % to 85 wt % relative to a total weight of the achiral component T, wherein R 1 is hydrogen, or C 1-20 alkyl in which arbitrary —CH 2 — is optionally replaced by —O—, —S—, —COO—, —OCO—, —CH═CH—, —CF═CF— or —C≡C— with a proviso that —O— is not adjacent to —CH═CH— and —CO— is not adjacent to —CH═CH—, and in the alkyl and the alkyl in which arbitrary —CH 2 — is replaced by —O—, —S—, —COO—, —OCO—, —CH═CH—, —CF═CF— or —C≡C—, arbitrary hydrogen is optionally replaced by halogen; L Z X
