1. A light emitting assembly comprising at least a light emitting panel member having a light emitting surface, at least one light source, at least one film, sheet, plate or substrate positioned near the light emitting surface through which light from the panel member is emitted, and an air gap between the film, sheet, plate or substrate and the panel member, wherein at least one surface of the film, sheet, plate or substrate has one or more reflective or refractive surfaces, and at least one of the reflective or refractive surfaces has well defined optical elements or deformities for controlling the emitted light such that at least some of the light is redirected to pass through a liquid crystal display with low loss.
