PROBLEM TO BE SOLVED: To provide a reflective screen that improves manufacturing efficiency, reduces manufacturing cost, and provides a uniform brightness distribution across the screen, and to provide an image display system.SOLUTION: A reflective screen 20 displays an image on a surface thereof by reflecting image light projected by an image source LS and includes; a lens layer 23 comprising a plurality of unit optical shapes 231, each being convex on a rear side opposite an image light source LS side and extending in a vertical direction of the screen, arrayed in a horizontal direction of the screen along the surface thereof; a reflective layer 22 formed on the rear side of the lens layer 23; and a light control layer 25 provided on the image source side of the lens layer 23 and comprising first light transmissive sections 252 and second light transmissive sections 253, which transmit light, alternately arrayed in the vertical direction of the screen along the surface thereof. Each second light transmissive section 253 has a wedge-shape having a width that is greatest at an end on the image source side and gradually decreases toward the rear side in a cross-section that is parallel to a thickness direction and to the vertical direction of the screen.SELECTED DRAWING: Figure 2 |
