PROBLEM TO BE SOLVED: To provide a simple and easily practicable window display method where the pattern of the video of animation is projected for decorative illumination at night in the Christmas season or the like or for other decoration as illumination from a window, or, even in the case of still pictures, displays are frequently changed, and also to provide a screen applied to the method. SOLUTION: Projected light from a projector 10 is discretely condensed in each condensing region in an effective display region 23 including many discrete arrayed lens parts provided on a screen, and the video is reprojected as the video which is made high in luminance even while the resolution is reduced.
