Abstract:
1. A projection screen for displaying an image by reflecting projected imaging light, comprising: a polarized-light selective reflection layer that selectively reflects a specific polarized-light component and comprises at least two partial selective reflection layers laminated to each other; wherein: each of the partial selective reflection layers has a structure for selectively reflecting a specific polarized-light component; each of the structures of the partial selective reflection layers is configured so that the partial selective reflection layers selectively reflect light in different wave ranges for red (R), green (G) and blue (B) colors; and in the polarized-light selective reflection layer, the partial selective reflection layer that selectively reflects light in the green (G) color wave range is situated farthest from the imaging-light-incident side of the projection screen relative to the other partial selective reflection layers.
