Abstract
A front-projection screen can include a substrate having first and second opposing sides with an array of optical microstructures on the first side of the substrate and an image reflecting layer on the second side of the substrate opposite the array of optical microstructures. An optically absorbing layer is located between the image reflecting layer and the array of optical microstructures, the optically absorbing layer includes an array of apertures therein exposing portions of the image reflecting layer therethrough.
