OPTICAL FILM, COMPOSITION, PLANAR IMAGE DISPLAY DEVICE, THREE DIMENSIONAL IMAGE DISPLAY DEVICE, LIQUID CRYSTAL DISPLAY DEVICE, ORGANIC EL DISPLAY DEVICE, AND METHOD FOR PRODUCING OPTICAL FILM

摘要

Provided is an optical film which exhibits excellent wet heat durability and has a supporting body with a good surface state. Also disclosed are: a composition which is suitable for use in the production of this optical film; a method for producing this optical film; and a planar image display device, a three dimensional image display device, a liquid crystal display device and an organic EL display device, each of which uses this optical film. This optical film comprises a supporting body, an alignment film and an optically anisotropic layer containing a liquid crystal compound in this order, and the alignment film contains a polyvinyl alcohol having a polymerizable group and a polyfunctional acrylamide-based compound that is selected from among polyfunctional acrylamide compounds and polyfunctional methacrylamide compounds.
