A transmission screen through which an observer can see the side of the screen opposite to the observer side, and which has a sufficient viewing angle is provided. The transmission screen is a transmission screenhaving a light diffusing layercomprising a transparent binder and light diffusing elements contained in the binder, and the transmission screen is constituted so that the light diffusing elements should have a relative refractive index n of 0.75 or smaller or 1.25 or larger relative to refractive index of the transparent binder, both surfaces of the transmission screenshould be substantially smooth, and the transmission screen should have a total haze (JIS K7136:2000) of 10 to 85%.

Transmission screen

A transmission screen having a writable and erasable surface for one side is provided. This transmission screen is constructed so that the writable and erasable surface should have a specular gloss (JIS K5600-4-7:1999) of 70 to 135%, the transmission screen as a whole should have a haze (JIS K7136:2000) of 80% or more, and the surface opposite to the writable and erasable surface should have a specular gloss (JIS K5600-4-7:1999) of 10% or less. With this transmission screen, writing with a marker for white boards and erasing can be easily done while seeing images projected on the transmission screen, and the images from a projector do not become hard to see due to projection of the images on the body of a writer.
