PURPOSE: A projection display screen is provided to prevent a defect of an image by refracting and scattering the image projected from a projector or a slider through beads of a dispersing plate. CONSTITUTION: A projection display includes a screen(1) for displaying an image, and a projector for projecting the image to the screen(1). The image projected from the projector is focused on the screen(1) while being refracted and scattered through beads irregularly aligned on a base film(13). The base film(13) forms a dispersing layer(15). A substrate(11) is installed front and/or rear portions of the dispersing plate so as to cover the dispersing layer(15). It is also possible to directly coat the dispersing layer(15) to the surface of the substrate(11) while removing the base film(13).72076 |
