摘要:
A screen for displaying an image by projection light includes: a selectively reflective layer having reflection properties with respect to light in a specific wavelength region corresponding to the projection light, and having absorption properties with respect to light in a wavelength region other than the specific wavelength region. And the selectively reflective layer includes an optical multilayer film having a dielectric film and a light-absorbing thin film having transmission properties, and a reflective layer for reflecting light which has passed through the optical multilayer film.
