ORGANIC LIGHT EMITTING DIODE AND A FABRICATION METHOD THEREOF

摘要

PURPOSE: An organic light emitting diode and a manufacturing method thereof are provided to efficiently discharge heat from a device by forming a graphene multilayer structure with a thickness of a nanometer scale on a hole injection layer. CONSTITUTION: An anode(2) is formed on a substrate(1). A thin film layer(12) including a graphene is formed on the anode. A light emitting polymer layer(4) is formed on the thin film layer. A cathode(6) is formed on the light emitting polymer layer. A hole injection layer(3) is formed between the anode and the thin film layer including the graphene.
