Abstract: An OLED display and a method of manufacturing thereof are disclosed. In one aspect, the display includes a scan line formed over a substrate and configured to transfer a scan signal, a data line and a driving voltage line crossing the scan line and respectively configured to transfer a data voltage and a driving voltage, and a switching transistor electrically connected to the scan line and the data line and including a switching drain electrode configured to output the data voltage. The display also includes a driving transistor including a driving gate electrode, a driving drain electrode, and a driving source electrode electrically connected to the switching drain electrode. The display further includes a storage capacitor including a first storage electrode electrically connected to the driving gate electrode and a second storage electrode formed on the same layer as the driving voltage line.
