A reflective projection screen for receiving images, for a projector having short focal length of short projection distance, and particularly a reflective projection screen applicable to 2D and 3D imaging. The reflective projection screen has multi-incident angles where every reflection surface is prepared from a projection angle of the projected image and where incident angles are formed differently from each reflection surfaces so that the projection images from different angles are reflected into one direction. |
