Dichroic dye, dye composition thereof, microencapsulated liquid crystal containing dichroic dye, liquid crystal composition and liquid crystal display device

摘要

Dichroic dyes, compositions thereof, and liquid crystal compositions, microencapsulated liquid crystal compositions and liquid-crystal display elements employing the same. The dichroic dyes have high photostability in addition to excellent solubility. Furthermore, the liquid crystal composition employing the above dichroic dyes can have an orientational order parameter more than 0.7.
