A reflection type projecting screen includes a diffuse plate having a diffuse transmission surface for converting at least transmission light into diffused light and a corner cube array for reflecting the light passing through the diffuse plate to a position which is approximately similar to a passing position of the diffuse transmission surface. The diffuse plate and the corner cube array are positioned in an order of the diffuse plate and the corner cube array. The reflection screen is capable of improving utilization efficiency of light and simplifying the structure while reducing the effect of outside light. Furthermore, there are provided a front projector system and a multi-vision projector system each of which has a projector for projecting the projection light and a reflection screen for reflecting the projection light as diffused light having directivity in at least one predetermined direction, in accordance with the incident direction of the projection light.
