METHOD FOR PRODUCING OPTICAL FILM, OPTICAL FILM, LAMINATED POLARIZING PLATE, AND IMAGE DISPLAY |
摘要 |
A method for producing an optical film including a birefringence layer having a refractive index distribution that satisfies nx>nz>ny, by which productivity of an optical film becomes high because there are a few steps, and a contamination is reduced, is provided. The method for producing an optical film including a birefringence layer includes forming an applied film by applying a birefringence layer forming material containing a non-liquid crystalline material with a birefringence (&Dgr;nxz) in the thickness direction thereof of 0.0007 or more directly on a shrinkable film, and forming a birefringence layer having a refractive index distribution that satisfies nx>nz>ny by shrinking the applied film through shrinking the shrinkable film.
