OPTICALLY ANISOTROPIC FILM

摘要

Provided is an optically anisotropic film high in transparency. The film is an optically anisotropic film having a refractive index relationship of nz>nx>ny wherein: nz represents a refractive index of an index ellipsoid which the optically anisotropic film forms, the refractive index being the refractive index thereof in a direction vertical to a plane of the film; nx represents another refractive index of the index ellipsoid, the refractive index being the main refractive index thereof in a direction parallel to the plane of the film; and ny represents still another refractive index of the index ellipsoid, the refractive index being the refractive index thereof in a direction parallel to the plane of the film and perpendicular to the direction related to the refractive index nx. The film further includes a polymer of a polymerizable liquid crystal compound, and an organic modified polysiloxane.
