Abstract
An anti-glare device for a transmission screen includes a layer of transparent material having a front surface and a back surface. The front surface is provided with a saw-toothed profile, while the back surface is bonded to a circular polarizer. By mounting the anti-glare device a predetermined distance in front of a transmission screen, glare due to ambient light can be substantially eliminated without producing echo images.
