ABSTRACT:
A screen includes a screen main body, having flexibility, onto which an image light is projected; a first support and a second support which, extending one along each of a pair of opposed edges of the screen main body, each support one of the pair of edges; an auxiliary support which, being disposed between the first support and the second support, extends parallel to the first support and the second support, and supports a pair of intersecting edges intersecting with the pair of edges of the screen main body; and linkage mechanisms which, bridging adjacent supports, among the first support, second support, and auxiliary support, as well as regulating a movement of the adjacent supports in an out-of-plane direction of a projection surface of the screen main body, extend and contract in a direction in which the adjacent supports face each other, bringing the adjacent supports closer to and away from each other.
