    摘要: An organic light emitting diode display is described which includes a substrate having a display area and a non-display area; a metal layer disposed on the non-display area of the substrate, an insulating layer, a voltage line disposed on the gate insulating layer and receiving a driving voltage, a second voltage line disposed on the gate insulating layer and receiving a low driving voltage, an organic insulating layer, and a cathode electrode disposed on the organic insulating layer. The second voltage line and the cathode electrode are electrically connected to each other through an opening formed in the organic insulating layer, and the first voltage line or the second voltage line is electrically connected to the metal layer through an opening formed in the gate insulating layer.
