    摘要： Provided are a projection image display member having a high visible light transmittance, suppressing a double image of a display image, and having excellent suitability of polarized sunglasses for incident light reflected from external light, a windshield glass using the projection image display member, and a head-up display system. The problem is solved such that one or more phase difference layers, one or more selective reflection layers, and one or more polarization conversion layers are provided in this order, the polarization conversion layer being a layer in which a helical alignment structure of a liquid crystal compound is fixed, and the number of pitches x of the helical alignment structure and a film thickness y (μm) of the polarization conversion layer satisfying “0.3≤x≤7.0”, “0.5≤y≤6.0”, “y≤0.7x+3.2”, and “y≥0.7x−1.4”.

    摘要： 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.
