Patent ID: 8531101

Claim:
An organic electroluminescent lighting element array disposed on a substrate, the organic electroluminescent lighting element comprising: a plurality of first electrodes separately disposed on the substrate, the first electrodes having a first refraction index; a patterned scattering layer disposed among the first electrodes on the substrate and located on edge portions of the first electrodes, wherein the patterned scattering layer has a second refraction index, and the second refraction index is greater than or substantially equal to the first refraction index; a plurality of auxiliary electrodes separately disposed on the patterned scattering layer, each of the auxiliary electrodes being electrically connected to one of the first electrodes, respectively; a patterned dielectric layer covering the auxiliary electrodes and having a plurality of contact holes, each of the contact holes respectively exposing one of the auxiliary electrodes; a plurality organic electroluminescence layers, each of the organic electroluminescence layers being respectively disposed on one of the first electrodes; and a plurality of second electrodes disposed on the organic electroluminescence layers, each of the second electrodes being respectively disposed on one of the organic electroluminescence layers and extending above one of the auxiliary electrodes adjacent thereto, and each of the second electrodes being electrically connected to the one of the auxiliary electrodes adjacent thereto by one of the contact holes.
