ABSTRACT:
A manufacturing method of an organic light emitting diode (“OLED”) includes forming an anode on a substrate, forming an inorganic buffer layer on the anode, forming a hole transport layer on the buffer layer, forming a light emission layer on the hole transport layer, forming an electron transport layer on the light emission layer, and forming a cathode on the electron transport layer. The forming an inorganic buffer layer includes thermal evaporation and oxidation.
