Abstract: Disclosed is a reflecting screen configured to reflect an image introduced from a projector. The reflecting screen includes a black resin layer having a dark color, wherein the black resin layer includes a plurality of slopes formed at one surface thereof so as to face in a given direction, the slopes being arranged in the vertical direction, and stepped portions formed between the slopes, corrugations formed at the slopes, and a reflecting layer formed at the slopes of the black resin layer. The reflecting screen is capable of reducing raw material costs and manufacturing costs and reducing the weight and volume of a product, as a result of simplifying a multilayered structure of a reflecting screen.

Abstract: A screen for displaying an image received from a projector includes an anisotropic base diffusion layer having a fine pattern; a lens layer formed on a rear surface of the anisotropic base diffusion layer; a reflection layer deposited on a rear surface of the lens layer; and a surface protection layer coupled with a front surface of the anisotropic base diffusion layer. The screen for a projector enables a viewer to view an image from a single focus projector inside a bright room, brightness to be uniformly distributed throughout the screen, and a desirable viewing angle to be obtained.
