Display device having partial overlap between opening of pixel defining layer and via hole

An electronic device comprising:

• a substrate including an emission area and a non-emission area;
• a driving voltage line disposed in the non-emission area;
• a via layer disposed on the driving voltage line, the via layer including:
• a first via hole exposing a first driving voltage line edge side of the driving voltage line, and
• a second via hole spaced apart from the first via hole;
• a first-first electrode, a first-second electrode, and a first-third electrode disposed on the via layer in the emission area and spaced apart from each other;
• a pixel defining layer disposed on the first-first electrode, the first-second electrode, and the first-third electrode and the via layer, the pixel defining layer including:
• a first opening disposed in the emission area and exposing a portion of each of the first-first electrode, the first-second electrode, and the first-third electrode, and
• a second opening spaced apart from the first opening and disposed in the non-emission area;
• a first emission layer disposed on the first-first electrode;
• a second emission layer disposed on the first-second electrode;
• a third emission layer disposed on the first-third electrode;
• and
• a second electrode disposed on the first emission layer, the second emission layer, and the third emission layer and the pixel defining layer, wherein
• the first emission layer, the second emission layer, and the third emission layer emit different colors of light,
• the second opening of the pixel defining layer and the first via hole of the via layer partially overlap each other in the non-emission area, and
• the via layer covers a second driving voltage line edge of the driving voltage line, the second driving voltage line edge being opposite the first driving voltage line edge.
