Zusammenfassung:A top-emitting pixel device is disclosed. The pixel device may include a reflective bottom electrode disposed over a substrate, a first charge transport layer disposed over the reflective bottom electrode, an emissive layer disposed over the first charge transport layer, and a second charge transport layer disposed over the emissive layer. Further, the pixel device may include a patterned transparent polymer electrode disposed over the second charge transport layer and extending laterally to cover an emissive area of the top-emitting pixel device, and a patterned auxiliary electrode disposed at least partially over the patterned transparent polymer electrode outside of the emissive area of the top-emitting pixel device to make direct electrical contact with the patterned transparent polymer electrode.
