MULTI-LAYER ANODE AND TOP EMISSION ORGANIC LIGHT EMITTING DIODE INCLUDING THE MULTI-LAYER ANODE

摘要

A multi-layer anode and a top emission organic light emitting diode including the multi-layer anode are provided to manufacture a conductive metal thin film as an anode electrode of the top emission organic light emitting diode. A top emission organic light emitting diode(10) includes a substrate(11), an anode(12), a hole injection layer(13a), a hole transporting layer(13b), a light emitting layer(14), an electron transporting layer(15a), an electron injection layer(15b), a cathode, a buffer layer(16), and a passivation layer(17). The anode is formed on the substrate. The hole transporting layer and the hole injection layer are formed on the anode. The cathode is formed on the electron injection layer. The buffer layer is formed on the cathode. The anode has a multi-layer structure. The anode includes a lower conduction layer(12a), a reflective conduction layer(12b), and an upper conductive layer(12c). The lower conductive layer is in direct contact with the substrate. The reflective layer is formed on the lower conduction layer. The upper conduction layer is formed on the reflective conduction layer.
