A flat-panel projection display comprises a tapered transparent slab (1), a projector (2) adapted to inject images into the thick end of the slab, a translucent screen (3) over the face of the slab from which the display is to be viewed, and spacers holding the screen away from the slab so that light emerging from the face of the slab can spread to cover the area of the screen. In this way the gaps or blank strips that would otherwise be present at the points where the light bundles are being reflected off the rear surface of the tapered waveguide are eliminated.
