SCREEN AND DISPLAY/IMAGING DEVICE

摘要

The present invention improves the light usage efficiency of image light. A screen according to one configuration of the present invention includes: a polarized light scattering layer that scatters horizontally-polarized light; a polarizing layer that blocks horizontally-polarized light and transmits vertically-polarized light; and a reflective layer that is disposed between the polarized light scattering layer and the polarizing layer. The reflective layer reflects light in accordance with the wavelength or polarization direction thereof so as to selectively reflect horizontally-polarized image light to be projected onto the screen.

主权项

1. A screen for reflecting projected image light of a first polarization direction, the screen comprising:
a polarized light scattering layer that scatters polarized light of the first polarization direction; a polarizing layer that blocks polarized light of the first polarization direction and transmits polarized light of a second polarization direction that is orthogonal to the first polarization direction; and a reflective layer disposed between the polarized light scattering layer and the polarizing layer, wherein the reflective layer reflects light according to wavelength and/or polarization direction so as to selectively reflect said image light.
