发明名称 Front projection screen
摘要 A front projection screen includes front and rear refractive facets. The rear refractive facets are coated with refractive coating layers for reflecting an image light which has penetrated through the front refractive facets toward the front refractive facets. Upper and lower flanks are disposed at both upper and lower side surfaces of the rear refractive facets. Penetrative coating layers are formed on the lower flanks. A light-absorbing member is disposed between the penetrative coating layers and the upper flanks so as to absorb the illumination light (noise light).
