Title:
OPTICAL ANISOTROPIC FILM
Document Type and Number:
Japanese Patent JP2015129922
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an optical anisotropic film having high transparency.SOLUTION: The optical anisotropic film has a relationship of refractive indices represented by nz>nx>ny and comprises a polymerized product of a polymerizable liquid crystal compound and an organic modified polysiloxane. In the expression, nz represents a refractive index in a direction perpendicular to the film plane in an index ellipsoid given by the optical anisotropic film; nx represents a principal refractive index in a direction parallel to the film plane in the index ellipsoid given by the optical anisotropic film; and ny represents a refractive index in a direction parallel to the film plane and orthogonal to the direction of nx in the index ellipsoid given by the optical anisotropic film.
