ABSTRACT:
Novel liquid crystal compositions are disclosed. One of them comprises at least a dichroic dye having a substituent containing three or more cyclic moieties, and a dual-frequency switchable nematic liquid crystal as a host liquid crystal; and another one comprises a dichroic dye having a substituent containing three or more cyclic moieties, and a liquid crystal comprising at least one nematic liquid crystal compound and at least one chiral agent. A novel liquid crystal device, comprising a pair of electrodes of which at least one is a transparent electrode and a layer between the pair of electrodes comprising one of the liquid crystal compositions, is also disclosed.
