Title:
光学積層体の製造方法、表示装置の製造方法
Document Type and Number:
Japanese Patent JP7016412
Kind Code:
B2
Abstract:
The present invention provides a method for manufacturing an optical laminate, whereby an optical laminate containing a surface film, a light absorption anisotropic layer, and an optically anisotropic layer can be easily manufactured, and a method for manufacturing a display device. This method for manufacturing an optical laminate comprises: a step for laminating a first optical laminate, which comprises a first peelable support, a first alignment film, and a light absorption anisotropic layer in said order, and a second optical laminate, which comprises a second peelable support, a second alignment film, and an optically anisotropic layer in said order, such that the surface on the light absorption anisotropic layer side of the first optical laminate faces the surface on the optically anisotropic layer A side of the second optical laminate, and peeling off the first peelable support to obtain a laminate X; and a step for laminating a surface film on the surface on the first alignment film side of the laminate X, and peeling off the second peelable support to obtain an optical laminate comprising the surface film, light absorption anisotropic layer, and optically anisotropic layer A.
