Liquid crystal composition and liquid crystal device

摘要

A novel liquid crystal composition is disclosed. The liquid crystal composition comprises at least one dual-frequency switchable smectic liquid crystal, and at least one dichroic dye. And a novel liquid crystal device is also disclosed. The device comprises a pair of electrodes of which at least one is a transparent electrode, and a liquid crystal layer between the pair of electrodes comprising a liquid crystal composition comprising at least one dual-frequency switchable smectic liquid crystal, and at least one dichroic dye.
