Organic light emitting diode display and manufacturing method thereof

An organic light emitting diode display device comprising:

• a substrate;
• a scan line formed over the substrate and configured to transmit a scan signal;
• a data line crossing the scan line configured to transmit a data voltage;
• a driving voltage line crossing the scan line when viewed in a viewing direction and configured to transmit a driving voltage;
• a switching transistor connected to the scan line and the data line;
• a driving transistor connected to the switching transistor;
• a driving connector member connected to a driving gate electrode of the driving transistor;
• a storage capacitor comprising a first storage electrode and a second storage electrode;
• a pixel electrode electrically connected to the driving transistor;
• and
• a contact hole connecting the first storage electrode and the driving connector member,
• wherein, when viewed in the viewing direction, the second storage electrode comprises a curved edge at least partly surrounding the contact hole, wherein the pixel electrode is formed not to overlap the curved edge when viewed in the viewing direction, and
• wherein the first storage electrode and the driving gate electrode are integrated in a single piece which overlaps the second storage electrode.
