Screen for projection television

Abstract

A screen of a projection television may include a Fresnel lens for converting an incident light beam emitted from an image source into a parallel beam, a lenticular lens formed by sequentially arranging multiple lens elements having a column shape parallel to one another for forming an image from the parallel beam output from the Fresnel lens and spreading the formed image, and a protective panel installed on the front surface of the lenticular lens for protecting the lenticular lens. The Fresnel lens may include a base substrate and a lens unit contacting one side of the base substrate, patterns having a saw-toothed shape formed on a surface of the lens unit facing a lenticular lens, and portions of each pattern corresponding to a sharp portion of a sawtooth may be a processed curved surface having a predetermined curvature.
