1. An array substrate, comprising:
a substrate;
a common electrode line disposed on the substrate;
a gate insulation layer disposed on the common electrode line;
a first passivation layer disposed on the gate insulation layer;
a common electrode disposed on the first passivation layer;
a second passivation layer disposed on the common electrode; and
a pixel electrode layer disposed on the second passivation layer,
wherein the pixel electrode layer comprises a pixel electrode and a bridge electrode insulated from the pixel electrode, a first through hole is opened in the common electrode, a second through hole is opened in the first passivation layer, a third through hole is opened in the gate insulation layer, the third through hole exposes the common electrode line, an orthographic projection of a hole wall of the first through hole on the substrate is a first orthographic projection, an orthographic projection of a hole wall of the second through hole on the substrate is a second orthographic projection, the first orthographic projection partially overlaps the second orthographic projection, the first through hole, the second through hole, and the third through hole are connected with each other, and the bridge electrode extends into the first through hole, the second through hole, and the third through hole to connect with the common electrode and the common electrode line;
wherein a length direction of the second orthographic projection is defined as a first direction, a direction perpendicular to the first direction is defined as a second direction, and in the first direction and/or the second direction, at least one end of the second orthographic projection is located outside the first orthographic projection; and
in the second direction, at least one end of the first orthographic projection is located outside the second orthographic projection;
wherein the array substrate further comprises a metal pad, the metal pad is disposed between a side of the common electrode line away from the substrate and aside of the common electrode closer to the substrate, in the first direction, an orthographic projection of the metal pad on the substrate extends from outside the second orthographic projection into the second orthographic projection but not into the first orthographic projection.
