Abstract
Since a screen contains a diffusion agent, the diffusion agent changes polarization characteristics of picture light and degrades the stereoscopic image. Provided is a screen comprising a substrate shaped as a flat board; a reflective layer made of metal arranged on one surface of the substrate; and an exposure layer that is arranged on a surface of the reflective layer facing away from the substrate, is optically isotropic and transparent with respect to visible light, and has bumps and depressions formed in an exposed surface thereof. Also provided is a screen manufacturing method comprising providing a reflective layer on a substrate shaped as a flat board; and forming an exposure layer on a surface of the reflective layer facing away from the substrate, the exposure layer being optically isotropic and transparent with respect to visible light and having bumps and depressions formed in an exposed surface thereof.
