Abstract
A projection screen for displaying an image by reflecting imaging light projected from a projector, including a substrate and a projected-image-receiving layer formed on the substrate. The projected-image-receiving layer has the function of selectively reflecting a specific polarized-light component and the function of diffusing the specific polarized-light component. Further, the projected-image-receiving layer includes two or more selective reflection layers having different reflection wave ranges, and, of these selective reflection layers, the selective reflection layer having a reflection wave range covering the shorter wavelength side is situated apart from the observation side as compared with the selective reflection layer having a reflection wave range covering the longer wavelength side.
