Organic light emitting diode display and method for manufacturing organic light emitting diode display

An organic light emitting device comprising:

• a substrate;
• a first thin film transistor including a first active pattern positioned on the substrate and a first gate electrode positioned on the first active pattern;
• an organic light emitting element connected to the first active pattern;
• a capacitor electrode overlapping the first gate electrode of the first thin film transistor, and having a same edge as the first gate electrode;
• a second thin film transistor including a second active pattern connected to the first active pattern and a second gate electrode positioned on the second active pattern;
• a third thin film transistor including a third active pattern connecting between the first active pattern and the first gate electrode and a third gate electrode positioned on the third active pattern;
• a first scan line positioned on the second active pattern to respectively cross the second active pattern and the third active pattern and connected to the second gate electrode and the third gate electrode;
• a data line positioned on the first scan line to cross the first scan line and connected to the second active pattern;
• and
• a driving power source line positioned on the first scan line to be separated from the data line and to cross the first scan line and connected to the capacitor electrode and the first active pattern.
