Patent ID: 7110176

Claim:
A reflex-type screen for reflecting a light projected obliquely from a projector to a front of the reflex-type screen, comprising: a base material made of material which absorbs light, comprising: a projector side inclined plane that is provided at an angle so that light from said projection enters said projector side inclined plane; and a non-projector side inclined plane that is provided at an angle so that the light from said projection does not enter said non-projector side inclined plane, wherein said projector side inclined plane and said non-projector side inclined plane are located alternatively, so that said base material is formed to be saw-toothed shape; a white resin layer which is formed on said projector side inclined plane on said base material and reflects light; and a transparent diffusing layer which comprises transparent binder resin and diffusing agent, and is formed to cover said white resin layer; wherein said white resin layer reflects the light from said projector to the front of the reflex-type screen, and said non-projector side inclined plane absorbs almost of incident light, and said transparent diffusing layer diffuses light which is reflected by said white resin layer.
