PROBLEM TO BE SOLVED: To provide a screen that displays a high quality image by reducing a luminance change and nonuniform luminance even if a projecting position changes when light is projected from a close distance, and to provide a display system combined with a projection device. SOLUTION: The reflection type screen 100 shows an image projected from a projector 50 located in a close distance. This screen 100 includes: a first reflecting face 12A by which light rays projected from a position A are reflected substantially in the same direction; and a second reflecting face 12B by which light rays projected from a position B, different from the position A, are reflected substantially in the same direction.
