Abstract:
Disclosed herein is a light emitting device and method of manufacturing such a device 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. Further the chiral materials in each layer 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. The light emitting layers of the light emitting device can further comprise electroluminescent material that emits light into the band edge light propagation modes of the photonic crystal.

Claim (Index 20):
A method of manufacturing a light emitting device by solvent casting a plurality of chiral liquid crystalline layers on a substrate comprising the steps of:\n depositing a layer of liquid crystal alignment material on said substrate and processing said liquid crystal alignment material such that it aligns the molecules of a liquid crystal material coated over it; depositing a first chiral liquid crystalline layer comprising a chiral liquid crystal structure, a top surface formed by a top layer of molecules, and a bottom surface opposite said top surface formed by a bottom layer of molecules, on top of said layer of liquid crystal alignment material by solvent casting said first layer on top of said layer of liquid crystal alignment material such that said bottom surface is positioned adjacent to said layer of liquid crystal alignment material and said bottom layer of molecules of said first layer are aligned by said layer of liquid crystal alignment material; photopolymerizing said first chiral liquid crystalline layer after it is deposited on said substrate such that said chiral liquid crystal structure of said first layer is locked in place in a robust polymer matrix; depositing a second chiral liquid crystalline layer comprising a chiral liquid crystal structure, a top surface formed by a top layer of molecules, and a bottom surface opposite said top surface formed by a bottom layer of molecules, on top of said first chiral liquid crystalline layer by solvent casting said second chiral liquid crystalline layer on top of said first chiral liquid crystalline layer such that said top surface of said first chiral liquid crystalline layer is adjacent to said bottom surface of said second chiral liquid crystalline layer wherein said top layer of molecules forming said top surface of said first chiral liquid crystalline layer acts as a template aligning said bottom layer of molecules forming said bottom surface of said second chiral liquid crystalline layer; photopolymerizing said second chiral liquid crystalline layer once said bottom layer of molecules forming said bottom surface of said second layer is properly aligned; and repeating said steps of solvent casting on top of the preceding chiral liquid crystalline layer, aligning the bottom layer molecules of, and photopolymerizing any further of said plurality of chiral liquid crystalline layers.
