A transmission screen includes a Fresnel lens sheet through which light is projected
from a projector to a lenticular lens sheet arranged on a viewer side, as approximately
parallel light, and the lenticular lens sheet receiving light passing through the
Fresnel lens sheet, and emitting the approximately parallel light while horizontally
widening, by a group of cylindrical lenses which are horizontally in parallel,
wherein in at least one of the Fresnel lens sheet and the lenticular lens sheet,
on a surface of a light diffusing substrate, in which a light diffusing material
is dispersed, irregularities which constitute a lens section is formed, and in
the light diffusing substrate, dispersion density of the light diffusing material
differs in at least two layers in the thickness direction.
