    Abstract: A Fresnel lens sheet (1) for a transmission screen, having a Fresnel lens shape on one side and fine protrusions and recesses on the other side. The fine protrusions and recesses are formed when the shape of fine surface protrusions and recesses are transferred, the fine surface protrusions and recesses being obtained when a binder (5) containing fine particles (4) having a mean particle diameter of 20 µm or less is layered on a substrate (3). The Fresnel lens sheet (1) for a transmission screen has enhanced brightness because of low loss in quantity of light, has suppressed speckle, has no moire, and has suppressed ghost.
