Organic light emitting display device, driving method thereof, and manufacturing method thereof

1. A method for manufacturing an organic light emitting diode (OLED) display, the method comprising:

forming a first active pattern on a substrate;

forming a gate insulating layer;

forming a gate electrode overlapping at least a part of the first active pattern on the gate insulating layer;

forming an interlayer insulating layer;

forming a conductive layer pattern and an anode of an OLED, the conductive layer pattern covering the gate electrode and contacting a first power line on the interlayer insulating layer, the conductive layer being a second electrode of a shield capacitor with a first electrode including the gate electrode;

forming a pixel defining layer; and

forming the OLED by forming an organic emission layer and a cathode.

2. The method of claim 1 , wherein the conductive layer pattern is formed to entirely cover the first electrode.

3. The method of claim 2 , wherein the forming of an interlayer insulating layer includes:

forming a first interlayer insulating layer;

forming a conductive layer pattern contacting the gate electrode and the first power line; and

forming a second interlayer insulating layer,

wherein the conductive layer pattern contacting the first power line is formed to entirely cover the first electrode including the gate electrode and the conductive layer pattern contacting the gate electrode.

4. The method of claim 1 , wherein the gate electrode is a gate electrode of a driving transistor for supplying a driving current of the OLED corresponding to an input data signal.
