A rear projection screen which is essentially free from scintillation, said screen being composed of two essentially parallel screen surfaces lying in closely spaced apart relation, one of said surfaces comprising a refraction lens system composed of lens defining transparent articles contained in a plastic carrier coating, the other surface of said screen comprising either a second refractive lens system or a light transmissive matte surface which acts as a refractive system, said systems each acting to disperse light passing therethrough at different wave lengths to individually produce scintillation effects, said two systems jointly acting to counterbalance their respective scintillation effects to provide a screen which is essentially free from scintillation.
