METHOD FOR MANUFACTURING FILM PATTERNED RETARDER, FILM PATTERNED RETARDER, AND POLARIZING PLATE AND IMAGE DISPLAY USING THE FILM PATTERNED RETARDER

摘要

PURPOSE: A manufacturing method for a film patterned retarder, a film patterned retarder, and a polarizing plate and image display device having the same are provided to have a high-resolution orientation pattern and suppress the misalignment of the pattern caused by size changes. CONSTITUTION: A film patterned retarder has a film(16), an orientation film(14), and an optical anisotropic layer(12). The optical anisotropic layer equally or symmetrically arranges first and second phase difference regions. Each first and second phase difference region has a mutually orthogonal in-plane ground axis. The film includes an optical characteristic Re. The orientation film is processed with orientation in one direction on the surface, and includes first and second orientation control regions having different decomposition levels of a photo-acid generator.
