Abstract
An organic electroluminescent (OEL) lighting element disposed on a substrate includes a first electrode, a second electrode, an OEL layer, an auxiliary electrode, a patterned scattering layer, and a patterned dielectric layer. The second electrode is opposite to the first electrode having a first refraction index. The OEL layer is disposed between the first electrode and the second electrode. The auxiliary electrode is disposed between the first electrode and the second electrode, electrically connected to the first electrode, and separated from the OEL layer by a gap. The patterned scattering layer is disposed between the first electrode and the auxiliary electrode, covers the auxiliary electrode, and has a second refraction index greater than or substantially equal to the first refraction index. The patterned dielectric layer is disposed between the auxiliary electrode and the second electrode, covers the auxiliary electrode, and is disposed between the auxiliary electrode and the OEL layer.
