Zusammenfassung:	A rear projection screen has a viewer's side and a projection side on which the image of a source is projected so that the projected image is visible from the viewer's side through the screen. The rear projection screen has a lenticular lens formed on the viewing side and including a multiplicity of vertically extending lens units each being provided at its both sides with total reflection surfaces. The lenticular lens further includes a multiplicity of horizontally extending lens units which diffuse the light in the vertical direction. The angular field of vision is increased in the horizontal direction by the vertical lens units and also in the vertical direction by the horizontally extending lens units.
