Zusammenfassung:	A curved back-projection screen having an angle of curvature greater than 180°, such as a wrap-around cylindrical or dome screen. The screen includes a first layer and a second synthetic resin diffusing layer on the first layer, the second synthetic resin diffusing layer containing a light absorbing material and light diffusing particles embedded in a resin material, with the second synthetic resin diffusing layer having a value of the product of the absorption coefficient and thickness of between 0.1 and 2. The second synthetic resin diffusing layer can be applied by spraying.
