Display device and method of manufacturing the same

A display device comprising:

• a substrate comprising an emission area and a non-emission area;
• a first interlayer insulating layer on the substrate;
• a data conductor on the first interlayer insulating layer;
• a passivation layer on the data conductor;
• a pixel electrode layer on the passivation layer;
• and
• a shielding electrode between the data conductor and the pixel electrode layer, defining a first contact opening and a second contact opening, and located in the emission area and the non-emission area except the first contact opening and the second contact opening.

A method of manufacturing a display device, comprising:

• forming a data conductor on a substrate, the data conductor comprising a drain electrode of a first transistor, and a driving voltage line;
• forming an interlayer insulating layer covering the data conductor;
• forming a shielding electrode on the interlayer insulating layer;
• forming a passivation layer on the shielding electrode;
• forming a portion of a first contact hole and a portion of a second contact hole by etching the passivation layer;
• forming a first contact opening and a second contact opening by etching the shielding electrode;
• completing formation of the first contact hole and the second contact hole by etching the interlayer insulating layer;
• and
• forming a display element layer on the passivation layer, the display element layer comprising a first electrode coupled to the drain electrode of the first transistor through the first contact hole in the first contact opening, and a second electrode coupled to the driving voltage line through the second contact hole in the second contact opening.
