Organic electroluminescent device comprising electron showered hole injection layer, and method for preparing the same

摘要

invention electron shower processed hole injection layer including an organic electroluminescent device and a method for manufacturing the relates, more specifically, the positive electrode formed on the substrate; Formed on the anode, an electron shower processed hole injection layer; A hole transport layer formed on the hole injection layer; A light emitting layer formed on the hole transport layer; The electron injection layer is formed on the light emitting layer; An electron transport layer formed on the electron injection layer; And to an organic electroluminescent device and a method of manufacturing a cathode formed on the electron transport layer. ; According to the present invention, the hole injection layer by performing the electron shower process to the hole injection layer by removing impurities and increasing the electrical surface resistance, it is possible to provide the performance and life improved organic light emitting device and a method of manufacturing the same.
