摘要： A transmissive screen includes a diffusing plate 7 having two first diffusing layers 13 and 15, to which diffusing particles are added respectively, arranged with a second diffusing layer 14, to which diffusing particles whose particle size is smaller than that of the first diffusing layers 13 and 15 are added, in between. Accordingly, even in the case where a diameter of a projection pupil of a projection lens that projects light onto the transmissive screen is small, an image glaring when displaying a bright image can be controlled, while minimizing deterioration of gain, resolution and uniformity.

摘要： A Fresnel lens sheet comprising a Fresnel lens substrate and a Fresnel lens, whose surface of the light source side has an average pitch of 200 μm or smaller and ten point roughness of 3 to 15 μm, a rear projection screen obtained by assembling the Fresnel lens sheet and a lenticular lens sheet, and a process for producing these. With the use of the Fresnel lens sheet and the rear projection screen in accordance with the present invention, a labyrinth light inside the screen and a surface reflection are diffused effectively and a ghost caused by them is remarkably reduced. Accordingly, the rear projection television employing the Fresnel lens sheet and the rear projection screen of the present invention provides excellent images without ghost light.
