Title: Transreflectors, transreflector systems and displays and methods of making transreflectors

Abstract: Light emitting assembly includes at least one film, sheet, plate or substrate positioned between a light source and a display for redirecting at least some of the light emitted by the light source. One side of the film, sheet, plate or substrate may have a pattern of reflective or refractive surfaces or deformities and the other side may have corresponding or aligned optical deformities of well defined shape. Light emitted from the light source that strikes a reflective or refractive surface or deformity on the one side of the film, sheet, plate or substrate passes through the film, sheet, plate or substrate and is redirected by at least one corresponding optical deformity on the other side of the film, sheet, plate or substrate.
