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.
