Abstract
An object of the present invention is to provide a half-mirror film for displaying a projection image having high adhesiveness, a laminated glass in which wrinkle generation of the half-mirror film is suppressed or furthermore has high adhesiveness, and an image display system using the laminated glass. The problem is solved by providing a half-mirror film for displaying a projection image including a transparent support; and a selective reflection layer reflecting light in a wavelength selective manner, in which the transparent support has an absolute value of 10 nm or less of an in-plane phase difference at a wavelength of 550 nm and a heat seal layer disposed on an opposite surface of a surface having the selective reflection layer, the heat seal layer contains a thermoplastic resin, and a mixed layer in which components of the transparent support and the heat seal layer are mixed is formed between the transparent support and the heat seal layer.
