Abstract
The present invention provides an organic EL device, by which optical efficiency and stability of the organic EL device are enhanced by providing an anode of high reflectivity, high work function, superior environmental characteristic, and favorable corrosion resistance to a top-emission type organic EL device. The present invention includes an anode, an organic layer on the anode, and a cathode on the organic layer, wherein the anode comprises a reflective layer reflecting light emitted from the organic layer and a hole injection layer on the reflective layer injecting holes.
Claims8
