SCREEN AND DISPLAY/IMAGING DEVICE

摘要

The light-use efficiency of video light is improved. A screen (2) in one mode of this invention comprises a polarized-light scattering layer (3) that scatters horizontally polarized light, a polarizing layer (5) that blocks horizontally polarized light and passes vertically polarized light, and a reflecting layer (4) positioned between the polarized-light scattering layer and the polarizing layer. The reflecting layer reflects light depending on the wavelength or polarization direction thereof so as to selectively reflect horizontally polarized video light projected on the screen.
