A reflection screen capable of obtaining excellent viewing angle characteristics, excellent transparency, and excellent reflection characteristics, and an image display system including the same are provided. According to one aspect of the present invention, a reflective screen 10 that reflects a laser beam projected as image light and displays it in an observable manner, the first transparent base material 11, The transparent resin layer 12 provided on one surface of the transparent substrate 11 and having a plurality of convex portions 12a on the surface, and right circularly polarized light or left circularly polarized light provided on the surface of the convex portion 12a and having a specific wavelength A selective reflection layer 13 having a cholesteric liquid crystal structure that selectively reflects the laser light of FIG. 1 and a transparent coating layer that covers the surface of the selective reflection layer 13, the surface of the transparent coating layer 13 being flat, A reflective screen 10 is provided in which the refractive index of the transparent substrate 11, the refractive index of the transparent resin layer 12, and the refractive index of the transparent coating layer 14 are the same or substantially the same.
