Abstract:
1. A method for fabrication of an organic light emitting diode (OLED) display device comprising: providing a substrate divided into a light emission region outputting an image and a wiring region placed between a gate driving circuit unit and the light emission region and having a plurality of wirings formed therein; forming a switching thin film transistor (TFT) and a driving TFT on the substrate; forming first and second power wirings on the wiring region of the substrate; forming a planarization film on the substrate on which the switching and driving TFTs and the first and second power wirings are formed; forming an anode on the planarization film; forming a first power wiring pattern directly along a length of the first power wiring and connected to the first power wiring, and forming a second power wiring pattern directly along a length of the second power wiring and connected to the second power wiring, the second power wiring pattern having an extending portion to cover the driving TFT; forming a barrier rib demarcating a pixel region, and covering the first power wiring pattern and exposing a portion of the second power wiring pattern on the substrate on which the anode, the first power wiring pattern and the second power wiring pattern are formed; forming an organic light emitting layer on the substrate on which the barrier rib is formed; and forming a cathode connecting to the exposed portion of the second power wiring pattern on the organic light emitting layer.
