    摘要： Each of a plurality of Fresnel prisms 12 is formed so that a refractive surface 12 thereof includes a non-light incidence surface 12c upon which any light ray emitted from a projector 1 is not directly incident because it is intercepted by another Fresnel prism 12, the non-light incidence surface having an angle τ′ with a reflective surface 12b which is different from the prism apex angle τ of each of the plurality of Fresnel prisms. As a result, a light ray reflected by the refractive surface 12a of each of the plurality of Fresnel prisms without passing through the refractive surface can be preventing from emerging, as unnecessary light, toward the viewer's line of sight.

    摘要： A transmission screen has a refraction total reflection Fresnel lens plate, a stray light eliminating plate, and an image display plate. The stray light eliminating plate has a condensing lens array and black stripes. The array has unit lenses arranged at an incident plane of the transparent substrate in a periodic structure in an up-and-down direction. The black stripes have transparent sections placed near condensing light points of the unit lens and opaque sections around the condensing light points of the unit lenses. The sections are alternately arranged at the outgoing plane of the transmission substrate in a periodic structure in an up-and-down direction. The image display plate has lenticular lenses in which unit lenses are arranged in a periodic structure in a horizontal direction at an incident plane of the transmission substrate of a scattering characteristic capable of scattering light fluxes.
