A rear-projection screen for an ultra short throw projector includes a diffusing member to diffuse incident light having a specific angular range (AR) corresponding to a hotspot area generated on the rear-projection screen, and to transmit incident light having an angular range other than the specific angular range (AR). The diffusing member is provided at an area of the rear-projection screen where light having smaller incidence angle with respect to the rear-projection screen strikes the rear-projection screen.
