1. A light emitting assembly comprising a light source, a display, and a film, sheet, plate or substrate positioned between the light source and the display, wherein one side of the film, sheet, plate or substrate has a pattern of reflective or refractive surfaces or deformities, and the other side of the film, sheet, plate or substrate has corresponding or aligned optical deformities of well defined shape that are quite small in relation to a width of the other side, wherein at least some of the optical deformities on or in the other side of the film, sheet, plate or substrate are staggered and intersect each other over at least a portion of a height or depth of each of the intersecting optical deformities, and wherein light emitted from the light source that strikes a reflective or refractive surface or deformity on or in 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 or in the other side of the film, sheet, plate or substrate.
