  • LAMINATED OPTICAL FILM, LIQUID CRYSTAL PANEL, AND LIQUID CRYSTAL DISPLAY APPARATUS
    Publication number: 20100208177
    Abstract: The present invention provides a laminated optical film capable of contributing to thinning of each of a liquid crystal panel and a liquid crystal display apparatus and of simplifying its manufacturing steps, and a method of manufacturing the laminated optical film. The laminated optical film is used in a liquid crystal display apparatus and arranged on a viewer side of a liquid crystal cell. The laminated optical film includes: a polarizer; and a retardation layer which is arranged on one side of the polarizer, has a refractive index ellipsoid showing a relationship of nx>ny=nz, and has an in-plane retardation value Re[590] of 90 to 190 nm. An angle formed between an absorption axis of the polarizer and a slow axis of the retardation layer is 5 to 85°. The retardation layer is formed of a liquid crystal material, and the retardation layer is arranged to be closer to the viewer side than the polarizer is.
