To provide a high-luminance reflection type screen that can reduce a loss of image light emitted from a projector, and that can be easily manufactured.
The reflection type screen comprises a diffusing base material which comprises a transparent substrate and a light diffusing layer and whose refractive index is represented by 1.40 or more, a circular Fresnel lens whose optical center is deviated from a screen toward the side of the projector and pitch is 122 m and height is 30 m for instance, and a metal reflecting layer. In the reflection type screen, the light diffusing layer is configured in such a manner that one or more layers in which a transparent layer portion and a light diffusing layer portion are integrated and whose Hayes value is 70% are laminated. Further, the reflection type screen which is characterized by further giving a reflection preventing film layer to an observer surface can be provided. Further, a light absorbing layer can be given as well.
