A method of manufacturing an organic light-emitting diode, the method comprising:
- forming a first electrode over a substrate, the first electrode comprising a first metal;
- forming a first metal layer on the first electrode, the first metal layer comprising the first metal;
- forming a hole injection layer by forming a first metal compound layer on the first metal layer, the hole injection layer comprising a second metal compound layer and a second metal layer, the second metal layer being on the second metal compound layer, the second metal compound layer being formed by oxidizing the first metal layer through the first metal compound layer, and the second metal layer being formed by reducing the first metal compound layer through the first metal layer;
- forming an organic emission layer on the hole injection layer;
- and
- forming a second electrode on the organic emission layer.
