Abstract
A display panel comprising a display substrate having a display area and a pad area disposed around the display area. A connection wire is disposed on the pad area of the display substrate. A signal wire is disposed on the connection wire. A supporter is disposed between the display substrate and the connection wire. The connection wire directly contacts the supporter.
Claims26
A display panel comprising:
- a display substrate having a display area and a pad area disposed around the display area;
- a connection wire disposed on the pad area of the display substrate;
- a signal wire disposed on the connection wire;
- an insulating layer disposed between the display substrate and the signal wire;
- and
- a supporter disposed between the display substrate and the connection wire,
- wherein the connection wire directly contacts the supporter,
- wherein lowermost surfaces of the connection wire and the supporter are disposed directly on a same layer as each other,
- wherein a planar size of the signal wire is greater than a planar size of the connection wire and a side surface of the signal wire extends further outward than a side surface of the connection wire in a plan view, and
- wherein the insulating layer directly contacts a first portion of an inclined side surface of the connection wire and exposes an upper surface of the connection wire and a second portion of the inclined side surface of the connection wire.
