1. A display panel, having a display area and a peripheral area disposed adjacent to the display area, the peripheral area comprising a first side portion, a second side portion, and a third side portion,
wherein the display panel comprises:
a first substrate and a second substrate disposed opposite to each other;
a sealant coating area defined on the first side portion, the second side portion and the third side portion, and provided with a sealant; and
a display layer disposed between the first substrate and the second substrate,
wherein part of the display panel corresponding to part of the sealant coating area on the first side portion comprises:
a line unit disposed on the first substrate;
a first via hole defined on the line unit;
a conductive electrode disposed in the first via hole and contacting the line unit; and
a first insulating layer disposed in the first via hole and located between the second substrate and the conductive electrode, the first insulating layer covering the conductive electrode and the line unit,
wherein the line unit comprises a first metal layer and a second metal layer spaced apart from the first metal layer, and the first metal layer is connected to the second metal layer through the conductive electrode; and
the line unit extends to the second side portion and the third side portion, and part of the display panel corresponding to parts of the sealant coating area respectively on the second side portion and the third side portion comprises a plurality of second via holes defined on the first metal layer and a second insulating layer disposed in the second via holes.
