METHOD FOR PRODUCING OPTICAL LAMINATE, OPTICAL LAMINATE, POLARIZING PLATE AND ORGANIC EL DISPLAY DEVICE

摘要

The objective of the present invention is to provide: an optical laminate which is suppressed in film thickness unevenness of an optically anisotropic layer and is free from point defects; a method for producing this optical laminate; and a polarizing plate and an organic EL display device, each of which uses this optical laminate. An optical laminate according to the present invention comprises an optically anisotropic layer A and an optically anisotropic layer B. A method for producing an optical laminate wherein an optically anisotropic layer A and an optically anisotropic layer B are arranged to be in direct contact with each other. In this method for producing an optical laminate, both a composition a for forming the optically anisotropic layer A and a composition b for forming the optically anisotropic layer B contain a fluorine compound, and the optically anisotropic layer A and the optically anisotropic layer B are formed in this order under such conditions where the composition a and the composition b satisfy a specific relation of surface tension when the optically anisotropic layer B is formed using the composition b after the formation of the optically anisotropic layer A with use of the composition a.
