Objects are to provide a projection-image-displaying laminate film that enables, when used for, for example, a HUD, displaying of undistorted projection images of high-quality screen images, a laminated glass using the projection-image-displaying laminate film, and an image display system using the laminated glass. The objects are achieved with a projection-image-displaying laminate film including a half-mirror film including a selective reflection layer configured to wavelength-selectively reflect light, and a heat-sealing layer disposed on one surface of the half-mirror film, wherein the half-mirror film has a stiffness at 25° C. of 4.0 N·mm or less, and the heat-sealing layer has a thickness of 40 μm or less, contains a thermoplastic resin, and has a surface opposite from the half-mirror film, the surface having a static coefficient of friction of 1.0 or less.
