Patent ID: 8169700

Claim:
A reflective screen comprising: a projection surface on which an image light is projected; a plurality of unit structures provided on the projection surface, the plurality of unit structures each being formed of a concavely curved surface or a convexly curved surface; at least one first unit structure of the plurality of unit structures including a first reflection portion that reflects the image light incident thereon toward a preset field of view such that a first viewer within the preset field of view recognizes a projected image, the first reflection portion being provided on the concavely curved surface or on the convexly curved surface of the at least one first unit structure; and at least one second unit structure of the plurality of unit structures including a second reflection portion that reflects at least a part of the image light incident thereon toward a region outside the preset field of view such that a second viewer outside the preset field of view recognizes the projected image, the second reflection portion being provided on the concavely curved surface or on the convexly curved surface of the at least one second unit structure, wherein: the second reflection portion has a light transmissive member provided on a reflection surface that reflects light, and the image light is refracted in the light transmissive member so that at least part of the incident image light is reflected toward the region outside the preset field of view.
