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

An organic light emitting diode (OLED) display comprising:

• gate wires provided on a substrate extending in a first direction;
• data wires provided on the gate wires extending in a second direction that crosses the first direction;
• a pixel circuit comprising:
• a first thin film transistor connected to the gate wires and the data wire, the first thin film transistor comprising:
• a first active layer provided on a substrate, the first active layer including a channel area, a source area, and a drain area, the source area and the drain area being doped with an impurity, and the first active layer configured to connect the data wires and the organic light emitting diode, and
• a first gate electrode which is not doped with the impurity, and disposed on the first active layer, with sequentially layered first and second insulation layers disposed between the first gate electrode and the first active layer;
• a first capacitor connected with the data wires, the first capacitor comprising:
• a first capacitor electrode formed in the same layer where the first gate electrode is formed and electrically connected to the first gate electrode;
• and
• a second capacitor electrode provided on the first capacitor electrode, having a third insulation layer disposed therebetween, wherein the second capacitor electrode is in electrical contact with the data wires;
• and
• a second capacitor, connected with the gate wires, comprising:
