Electrostatic protection diode and organic light emitting display device including electrostatic protection structure

An organic light emitting display (OLED) device, comprising:

• a substrate comprising a pixel region comprising a plurality of pixel structures and a peripheral region comprising a plurality of wirings, the wirings being electrically coupled to the pixel structures, the peripheral region surrounding the pixel region;
• a first wiring in the peripheral region on the substrate, the first wiring having a first width;
• a second wiring on the first wiring, the second wiring intersecting the first wiring, the second wiring having a second width that is less than the first width;
• a third wiring spaced apart from the first wiring, the third wiring having a third width that is greater than the second width;
• and
• an electrostatic protection structure having electrostatic protection diodes, the electrostatic protection diodes being electrically coupled to the first, second, and third wirings, the electrostatic protection diodes each comprising:
• an active pattern in the peripheral region on the substrate, the active pattern having a first region, a second region spaced apart from the first region, and a third region located between the first and second regions;
• a gate electrode pattern in the third region on the active pattern;
• and
• a connection pattern on the gate electrode pattern, the connection pattern overlapping a portion of the first region of the active pattern and a portion of the third region, the connection pattern being electrically coupled to the gate electrode pattern and the active pattern.
