In order to provide a screen having a projection surface on which of
external light has little influence and has a large gain, as well as a
projection surface that has a wide viewing angle and nature-views, the
screen according to the present invention includes a directional
diffusion layer for diffusing and transmitting light from a specific
direction and linearly transmitting light from other directions, an
isotropic diffusion layer for approximately isotropically diffusing light
regardless of an incident angle thereof, and a light reflecting layer
provided between the directional diffusion layer and the isotropic
diffusion layer.
