Abstract

This invention provides a Fresnel lens sheet 1 for transmission type screen , characterized in that Fresnel shape is formed on one side and minute roughness is formed on the other side of the Fresnel lens sheet, the minute roughness being formed by the transfer of a minute roughness shape on the surface obtained by the lamination of binder 5 containing particle 4 with average diameter under 20 μm on the substrate 3, and its fabrication method.
