Disclosed herein are light emitting device that emit highly circularly polarized light. These devices may be used to form a dot-matrix display or an electronic information display comprised of a series of photopolymerizable, chiral liquid crystalline layers that can be solvent cast on a substrate. The mixture of chiral materials in each successive layer may be blended in such a way that each layer has the same chiral pitch and may also be blended so that the ordinary and extraordinary refractive indices in each layer match the other layers such that the complete assembly of layers will optically function as a single relatively thick layer of chiral liquid crystal. The chiral nematic material in each layer can spontaneously adopt a helical structure with a helical pitch. Further disclosed are pixel structures that not only emit light with brightness and chromaticity information, but also depth of focus information as well.
