Display device including a light emitting element connected to a first pad electrode and a second pad electrode and manufacturing method thereof

A display device comprising:

• a substrate including a display area and a non-display area;
• a pixel located in the display area, the pixel having an emission area and a pixel circuit area;
• and
• a dummy pixel located in the non-display area, the dummy pixel being spaced from the pixel,
• wherein the dummy pixel comprises:
• a first dummy pad electrode and a second dummy pad electrode that are spaced from each other;
• a first dummy power line;
• a first through hole and a second through hole;
• and
• a first light emitting element comprising a first bump metal in contact with the first dummy pad electrode through the first through hole and a second bump metal in contact with the second dummy pad electrode through the second through hole, the first through hole and the second through hole overlapping the first light emitting element,
• a first insulating layer, a second insulating layer, and a third insulating layer sequentially stacked on the substrate;
• and
• a dummy connection line between the third insulating layer and the first dummy pad electrode, the dummy connection line being electrically connected to the first dummy pad electrode,
• wherein the second through hole overlaps an active layer of the first light emitting element, and
• wherein the first through hole completely penetrates one region of the first dummy pad electrode and the dummy connection line and the second through hole completely penetrates one region of each of the second dummy pad electrode and the first dummy power line.
