PROBLEM TO BE SOLVED: To provide a reflective screen that makes a projected image visually recognizable, even in a region outside a preset field of view, while suppressing decrease in the brightness of the projected image, within a preset field of view. SOLUTION: The reflective screen 1 includes a plurality of unit structures 2 provided on a projection surface Sf, the unit structures formed of a concavely curved surface. The unit structures 2, each have a reflection portion 20 in at least part of the concavely curved surface in order to reflect image light R1. The reflection portion 20 of each of the unit structures 2 has a first reflection portion 20A for reflecting incident image light R1 toward a preset region of view of field and a second reflection portion 20B for reflecting, at least a part of the incident image light R1 toward a region outside the preset region.
