摘要
In a rear projection screen having a large horizontal viewing angle caused by the shape of the first light-spreading elements (51) provided at the front side of the plate (50) the color shift is corrected by providing second light-spreading elements (61) at the rear sside of the plate. The second light-spreading elements are aligned approximately parallel to the first light-spreading elements and have a pitch (p) which is considerably smaller than the pitch of the first light-spreading elements. This screen provides a good color correction while the first and the second light-spreading elements are formed in such a way that the screen can be manufactured on an industrial scale without any problem.
