Abstract
A display panel includes a display area, a pad area adjacent to the display area, pixels disposed in the display area on a substrate, and pads disposed in the pad area on the substrate and electrically connected to pixels. Each of the pads includes a first conductive layer, at least one a first protrusion disposed on the first conductive layer, at least one second protrusion disposed on the first conductive layer and having a thickness smaller than a thickness of the at least one first protrusion, and a second conductive layer disposed on the first conductive layer and overlapping an upper surface of each of the at least one first protrusion and an upper surface of the at least one second protrusion in a plan view.
Claims24
A display panel comprising:
- a display area;
- a pad area adjacent to the display area;
- pixels disposed in the display area on a substrate;
- and
- pads disposed in the pad area on the substrate and electrically connected to the pixels,
- wherein each of the pads includes:
- a first conductive layer;
- at least one first protrusion disposed on the first conductive layer;
- at least one second protrusion disposed on the first conductive layer and having a thickness smaller than a thickness of the at least one first protrusion;
- and
- a second conductive layer disposed on the first conductive layer and overlapping an upper surface of the at least one first protrusion and an upper surface of the at least one second protrusion in a plan view.
A display panel comprising:
- a display area;
- a pad area adjacent to the display area;
- pixels disposed in the display area on a substrate;
- and
- pads disposed in the pad area on the substrate and electrically connected to the pixels,
- wherein each of the pads includes:
- a first conductive layer;
- a first organic layer disposed on the first conductive layer;
- a second organic layer partially disposed on the first organic layer;
- and
- a second conductive layer disposed on the first conductive layer, overlapping an upper surface of the second organic layer in a plan view, and exposing at least a portion of a side surface of the second organic layer.
A display device comprising:
- a display panel including:
- a display area;
- a pad area adjacent to the display area;
- pixels disposed in the display area on a substrate;
- and
- pads disposed in the pad area on the substrate and electrically connected to the pixels;
- and
- a driving chip bonded to the pad area on the substrate and including bumps connected to the pads,
- wherein each of the pads comprises:
- a first conductive layer;
- a first protrusion disposed on the first conductive layer;
- a second protrusion disposed on the first conductive layer and having a thickness smaller than a thickness of the first protrusion;
- and
- a second conductive layer disposed on the first conductive layer and overlapping an upper surface of the first protrusion and an upper surface of the second protrusion.
