| titleOfInvention | Front projection screen |
| abstract | A screen of reflection-type operable with linearly polarized image-forming rays of light projected thereon for presenting a projected image, carried by the linearly polarized image-forming rays of light, to viewers occupying a position in front of the screen. The screen comprises a polarizing film (6) having first and second surfaces, a metal layer (4) formed on the second surface of the polarizing film (6) for reflecting the linearly polarized image-forming rays of light, and an indentation structure formed on both of the metal layer (4) and the polarizing film (6) for reflecting the image-forming rays of light uniformly at a desired angle of reflection. The linearly polarized image-forming rays of light enter the polarizing film (6) through the first surface thereof while the linearly polarized rays of light have a plane of vibration of an electric field or a magnetic field in a direction required to exhibit a maximum light transmissivity. The screen may also be operable with a bundle of image-forming rays of light projected from a projector (1) in the form of a cone of light as spherical waves onto the screen or a bundle of image-forming rays of light projected from a projector as plane or approximately plane waves onto the screen. |
