Organic light emitting diode display

An organic light emitting diode display, comprising:

• a substrate including a pixel region and a peripheral region enclosing the pixel region;
• a scan line on the substrate and transferring a scan signal;
• a data line crossing the scan line and transferring a data voltage;
• a switching transistor disposed in the pixel region and electrically connected to the scan line and the data line;
• a driving transistor disposed in the pixel region and electrically connected to the switching transistor;
• a pixel-area passivation layer disposed on the switching transistor and the driving transistor;
• a pixel electrode disposed on the pixel-area passivation layer;
• a pixel partition wall layer disposed on the pixel-area passivation layer and having a pixel opening overlapping the pixel electrode;
• an organic light emission layer disposed in the pixel opening and disposed on the pixel electrode;
• a common electrode disposed on the organic light emission layer and the pixel partition wall layer;
• a common voltage line disposed in the peripheral region and electrically connected to the common electrode;
• a peripheral passivation layer disposed in the peripheral region and contacting a side wall of the common voltage line;
• a surrounding driving voltage line disposed in the peripheral region and connected to the pixel electrode;
• a driving voltage pad to which the driving voltage ELVDD is applied from the outside;
• a driving voltage connecting part connecting the driving voltage pad and the surrounding driving voltage line,
• wherein the driving voltage pad is disposed at the same layer as the common voltage line.
