<p>PROBLEM TO BE SOLVED: To provide a reflection screen in which oxidation of metal constituting a reflection layer is suppressed to reduce the degradation of reflectance and exfoliation of the reflection layer from a lens layer.SOLUTION: The reflection screen includes at least a Fresnel lens layer in which a plurality of unit lenses having lens surfaces and non-lens surfaces and being convex to the rear side are arranged, a reflection layer provided on at least a part of the lens surfaces of the Fresnel lens layer to reflect light, and a back coat layer provided on the rear side of the reflection layer, and reflects image light projected from an image source to display it so that it can be observed. A barrier layer is provided between the reflection layer and the back coat layer.</p> |
