White organic electroluminescent device

An organic electroluminescent device, comprising:

• a first emissive layer comprising a non-emissive component and a first emissive component, wherein at least one of said first emissive component and said non-emissive component includes at least one of a polymer, polymer blend, and co-polymer, and wherein the other one of said first emissive component and said non-emissive component includes at least one of a polymer, polymer blend, monomer, oligomer, co-polymer, and an organic side-group, and wherein the first emissive layer is cross-linked, said first emissive component capable of emitting light in a first spectrum;
• a second emissive layer disposed over said first emissive layer, said second emissive layer comprising at least one secondary emissive component, wherein said at least one secondary emissive component includes at least one of a polymer, polymer blend, co-polymer, or at least one of a polymer, polymer blend, co-polymer in combination with at least one of a monomer, oligomer, and an organic side-group, and wherein the second emissive layer is cross-linked, said first emissive layer is insoluble to the material used in fabricating said second emissive layer, wherein said second emissive layer is capable of emitting light in a second spectrum;
• and
• a third emissive layer disposed over said second emissive layer, said third emissive layer comprising at least one tertiary emissive component, wherein said at least one tertiary emissive component includes at least one of a polymer, polymer blend, co-polymer, or at least one of a polymer, polymer blend, co-polymer in combination with at least one of a monomer, oligomer, and an organic side-group, said second emissive layer is insoluble to the material used in fabricating said third emissive layer, wherein said third emissive layer is capable of emitting light in a third spectrum, further wherein said first spectrum, second spectrum and third spectrum combine such that an output spectrum of said device is white.
