A screen onto which an image light may be projected includes a flexible screen body, a first and a second storage member, and a retention member. The first storage member includes a screen wind-up section that winds up the screen body and supports either one of opposing end portions of the screen body and a base body that supports the screen wind-up section. The retention member includes a substantially orthogonal column that extends along the screen body and a pair of arm members that couple the column and the first and second storage members together. One end of each of the arm members is respectively rotatably coupled to the first and second storage members and another end of each of the arm members is rotatably coupled to the column.
