A reflex-type screen for reflecting obliquely projected light from a projector to a front of the screen. The screen includes a light absorbing base material and a plurality of inclined planes disposed on the base material. The planes are arranged such that projected light do not enter non-projector side inclined planes, and the projector side and non-projector side planes alternate to form a saw-tooth shaped arrangement. A light reflecting white resin layer is disposed on the projector side planes to reflect light from the projector to the front of the screen. A transparent light diffusing layer including binding agent and diffusing agent is formed to cover the white resin layer and the base material, including all inclined planes. The non-projector side inclined planes absorbs incident light and the diffusing layer diffuses light reflected by the white resin layer.
