摘要： A reflex-type screen includes a base which has saw-tooth appearance, and an optical absorption layer on one edge of each saw-tooth of the base. The base consists of white resin and includes a plurality of projector side inclined planes and non-projector side inclined planes, which are alternately provided to form the saw-tooth appearance. The projector side inclined planes are oriented so that the image light from the projector may be incident on them, while the non-projector side inclined planes are oriented so that the image light from the projector may not be incident on them. The optical absorption layer is formed on each of the non-projector side inclined planes of the base to absorb the light. The projector side inclined plane reflects the image light just in front of the observer of the reflex-type screen from the projector.

摘要： 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.
