ABSTRACT:
A self-emissive display device. The display device comprises a substrate having a pixel region for displaying one of the primary colors. An organic electroluminescent multi-layer structure is disposed in the pixel region of the substrate. The organic electroluminescent multi-layer structure comprises a first micro-cavity portion and a second micro-cavity portion adjacent thereto. The first micro-cavity portion comprises an organic layer for light-emitting and a first film for determining light wavelength shift of the first micro-cavity portion. The second micro-cavity portion comprises the organic layer for light-emitting and a second film for determining light wavelength shift of the second micro-cavity portion. The first and second films have different optical lengths, such that the first and second micro-cavity portions provide opposite directions of the light wavelength shift.
