LONG PHASE DIFFERENCE FILM, LONG ELLIPTIC POLARIZATION FILM, ELLIPTIC POLARIZATION PLATE AND IMAGE DISPLAY DEVICE

摘要

Provided is a long elliptic polarization film having excellent productivity in manufacture and excellent view angle characteristics when used for an image display device and excellent color stability when stored in a high-temperature and high-humidity environment. A long phase difference film required for providing such long elliptical polarization film is also provided. Furthermore, an image display device using an elliptical polarization plate clipped from the elliptical polarization film is also provided. The long phase difference film is provided by arranging a vertically aligned liquid crystal layer on a long base material film composed of a transparent resin. The angle formed by the delayed phase axis within the surface of the base material film and the longitudinal direction of the film is 10-80°.
