Display device and method of manufacturing the same

A display device comprising:

• a substrate comprising a display area having a plurality of pixel areas and a non-display area located around the display area;
• a circuit element layer comprising a circuit element in each of the pixel areas and a reference voltage wiring in the non-display area, the reference voltage wiring being electrically coupled to the circuit element;
• and
• a display element layer comprising a first pixel electrode on the circuit element layer in each of the pixel areas, a second pixel electrode located opposite to the first pixel electrode, a plurality of light emitting elements between the first pixel electrode and the second pixel electrode, and a first wiring on the circuit element layer in the non-display area,
• wherein the first wiring is directly coupled to the reference voltage wiring in the non-display area,
• wherein the first wiring comprises:
• a body portion that extends in a first direction;
• and
• a protruding portion that protrudes from the body portion in a second direction intersecting the first direction, and
• wherein the protruding portion overlaps the reference voltage wiring, and the first wiring is coupled to the reference voltage wiring by the protruding portion.
