1. A display panel, comprising a display area and a non-display area adjacent to the display area;
wherein the display panel further comprises:
a substrate;
an array driving layer disposed on the substrate and located in the display area;
a bonding terminal disposed on the substrate and located in the non-display area;
a passivation layer disposed on the array driving layer and the bonding terminal, wherein the passivation layer comprises a first through hole and a second through hole, the first through hole exposes the bonding terminal, and the second through hole exposes a part of the array driving layer;
a covering layer disposed on the passivation layer, wherein a material of the covering layer comprises molybdenum titanium alloy or titanium and excludes Ag, the covering layer comprises a first covering portion and a second covering portion, the first covering portion is disposed on the passivation layer and connected to the bonding terminal through the first through hole, the second covering portion is connected to the array driving layer through the second through hole, and a height of the second covering portion is higher than a height of the first covering portion; and
an electrode layer disposed on the covering layer, wherein the electrode layer comprises a second electrode portion disposed on the second covering portion, wherein the second electrode portion is attached to the second covering portion, and an orthographic projection of the second electrode portion projected on the substrate is fully within an orthographic projection of the second covering portion projected on the substrate.
