Abstract
A motion-picture screen for projecting an optical image, which comprises a weaved knit having an adequate air permeability. One surface of the weaved knit is coated with a colored material so as to keep a high acoustic permeability concurrently with shutting the light from a wall or the like existing at the rear side of the screen. The other surface of the weaved knit is used as a surface onto which the optical image is projected by a projector, thereby providing an excellent contrast and a high image quality on the screen.
