Organic light emitting device and a method of fabricating thereof

A method of fabricating of an organic light emitting device comprising the following steps:

• providing a substrate;
• disposing an anode layer on the substrate;
• forming a hole injection layer on the anode layer by a first solution;
• forming an emitting material layer on the hole injection layer by a second solution, wherein the hole injection layer is insoluble in the second solution;
• forming an electron transport layer on the emitting material layer by a third solution, wherein the emitting material layer is insoluble in the third solution;
• and
• forming a cathode layer on the electron transport layer.

An organic light emitting device, comprising:
