Organic light emitting diode and method of fabricating the same

A method of fabricating an organic light emitting diode, comprising:

• forming a first electrode on a substrate;
• forming an emission layer on the first electrode;
• forming a second electrode on the emission layer;
• and
• forming a metal layer that includes a metal element and has a thickness of no less than 5 Å and less than 50 Å, the metal layer being formed between the first electrode and the emission layer or between the emission layer and the second electrode.

An organic light emitting diode comprising:

• a first electrode;
• a hole injection layer formed on the first electrode;
• a hole transport layer formed on the hole injection layer;
• an emission layer disposed on the hole transport layer , the emission layer emitting light;
• a metal layer disposed on the emission layer, the metal layer having a thickness no less than 5 Å and less than 50 Å;
• and
• a second electrode disposed on the metal layer.
