Abstract
A display device includes a substrate having a display area and a contact area located in the display area, a power line in the display area on the substrate, overlapping the contact area, and including a first conductive layer and a second conductive layer on the first conductive layer, a passivation layer on the substrate and the power line and having a protrusion protruding in a first direction with respect to an edge of an upper surface of the first conductive layer in the contact area, and a common electrode on the substrate and the passivation layer and electrically connected to the power line in the contact area.
Claims16
A display device comprising:
- a substrate having a display area and a contact area located in the display area;
- a power line disposed in the display area on the substrate, overlapping the contact area, and including a first conductive layer and a second conductive layer disposed on the first conductive layer;
- a passivation layer disposed on the substrate and the power line and having a protrusion protruding in a first direction with respect to an edge of an upper surface of the first conductive layer in the contact area;
- and
- a common electrode disposed on the substrate and the passivation layer and electrically connected to the power line in the contact area,
- wherein in the contact area, the passivation layer exposes a side surface of the first conductive layer, the side surface extending from the edge of the upper surface of the first conductive layer, and
- an undercut shape is defined in the contact area by the side surface of the first conductive layer and the protrusion.
