WIDE VIEWING ANGLE POLARIZING FILM

摘要

PROBLEM TO BE SOLVED: To provide a wide viewing angle polarizing film having good viewing angle characteristics in a wide visible light range.

SOLUTION: Regarding the wide viewing angle polarizing film constituted by laminating both an optical anisotropic film (A) having the maximum azimuth of a refractive index in a plane and an optical anisotropic film (B) having the maximum azimuth of the refractive index in a film thickness direction on one side of the polarizing film, a polymer orientation film with the wavelength dispersion of a phase difference being controlled is used as at least one of the film (A) and the film (B).
