Claim:
1. An organic light emitting diode (OLED) display comprising: a substrate; a scan line on the substrate and configured to transfer a scan signal; a data line crossing the scan line and configured to transfer a data signal; a first driving voltage line crossing the scan line, parallel to the data line, and configured to transfer a driving voltage; a second driving voltage line crossing the data line and the first driving voltage line, parallel to the scan line, and disposed in a different layer from, and electrically connected to, the first driving voltage line; a switching thin film transistor (TFT) connected to the scan line and the data line; a driving TFT connected to the switching TFT and the first driving voltage line; an OLED connected to the driving TFT; and a storage capacitor comprising: wherein the second driving voltage line overlaps with, and is electrically insulated from, the first storage capacitor plate that is electrically connected to a driving gate electrode of the driving TFT.
