Zusammenfassung:	Provided is a transmission type screen composed of a laminated body having a main light scattering layer containing a first light scattering agent; a base material layer, which is formed on the main light scattering layer and contains a second light scattering agent at a concentration lower than that of the first light scattering agent. A light transmission rate of the structure in the laminating direction is 70% or more and a contrast is 600:1 or more.
