A method of fabricating an organic light emitting diode display device, which include forming a thin film transistor in a display region of a substrate, forming a metal pattern on the substrate in the display region, forming a first electrode on the substrate connected to the thin film transistor, forming a bank on the substrate to expose a portion of the first electrode and a portion of the metal pattern, forming a hole common layer, an organic light emitting layer, and an electron common layer sequentially over the entire surface of the substrate provided with the first electrode, the bank and the metal pattern, forming a photoresist pattern covering the electrode common layer and removing the hole common layer, the organic light emitting layer and the electron common layer using the photoresist pattern as a mask, removing the photoresist pattern, and forming a second electrode on the electron common layer connected to the metal pattern.
