Abstract:
An object of the present invention is to provide a laminate in which an excellent alignment property of a dichroic substance is maintained and which is excellent in both high-temperature durability and moisture-heat resistance, a manufacturing method of the laminate, and an image display device using the laminate. A laminate according to an embodiment of the present invention is a laminate having a transparent support, a light absorption anisotropic film, and a transparent resin layer in this order, in which the light absorption anisotropic film is a film containing a dichroic substance represented by a predetermined formula, and the transparent resin layer is a layer containing a polymer which has a hydrophilic group and does not have a glass transition temperature in a temperature range of 95° C. or lower.
