Abstract: An organic light emitting device having an aluminum oxynitride interface layer and a method for manufacturing the same are provided to improve light emitting efficiency and to reduce driving voltage in comparison with an organic light emitting device without the interface layer. An organic light emitting device includes an anode(2), a hole transport layer(4), an interface layer(3), a light emitting layer(5), a buffer layer(6), and a cathode(7). The anode is formed on an upper part of a substrate(1). The hole transport layer is formed on an upper part of the anode. The interface layer is formed between the anode and the hole transport layer to facilitate hole injection from the anode to the hole transport layer and made of aluminum oxynitride. The light emitting layer is formed on an upper part of the hole transport layer. The buffer layer is formed on an upper part of the light emitting layer. The cathode is formed on an upper part of the buffer layer.
