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 (Δnxz) 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.

摘要： The optical laminated film of the present invention comprises a polarizer and a retardation film laminated on one surface of the polarizer, in which the polarizer has a drawn film of a hydrophilic polymer containing a dichroic material. An in-plane birefringence index (Δnxy[1000]) of this polarizer at wavelength of 1000 nm is from 0.01 to 0.03, and the retardation film is a film such that an index ellipsoid satisfies the relation of nx>ny≧nz. The retardation film is disposed so that the slow axis direction of the retardation film is substantially orthogonal to the absorption axis direction of the above polarizer.The optical laminated film of the present invention may increase contrast ratio in the case of being used for a liquid crystal display, for example.
