FIELD: projection TV. SUBSTANCE: aperture screen is made in form of transparent base 3 of Fresnel lens 4 and other light dissipators. Light dissipator is made in form of spherical transparent elements 1 and is disposed onto base 3 in form of monolayer. Thickness of monolayer does no exceed maximal diameter of these elements. Elements of light dissipator are disposed in monolayer according to preliminary specified law, for example, in combination with non-transparent elements, which increase contrast of image. Mesh of cylindrical transparent or opaque elements may be used. Pitch and optical characteristics of the mesh are specified preliminary. EFFECT: improved efficiency. 7 cl, 10 dwg
