Abstract:
1. A method of fabricating an organic light emitting diode display device, the method comprising: forming a thin film transistor in a display region of a substrate, the substrate having a display region and a non-display region; 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 photoresist pattern to cover the metal pattern, wherein an upper surface of the photoresist pattern is higher than an upper surface of the bank; 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 and the photoresist pattern; removing the photoresist pattern with material of the hole common layer, the organic light emitting layer, and the electron common layer on the upper surface of the photoresist pattern; and forming a second electrode on the electron common layer to be connected to the metal pattern.
