ABSTRACT OF THE INVENTION A heads-up display for moving vehicles such as an airplane or automobile includes a transparent sheet which may be the windscreen or windshield of the vehicle. An extremely thin enchacing film is secured in intimate contact with the transparent sheet and disposed either within the sheet, it it is a laminated sheet such as a safety glass sheet, or on that side of the sheet which is on the interior of the vehicle. The film is an absorber or blocker of selected light waves which match the light waves of a display of indicia projected against the interior side of the windscreen. The assembly of film and sheet eliminates the need for a separate, independent indicia reflector to be placed between the windscreen and the operator of the vehicle.
