1. An array substrate, comprising a first base substrate, a plurality of data lines, and a plurality of sub-pixels connected to the plurality of data lines, at least one of the plurality of sub-pixels comprising:
a first insulating layer located on one side of the first base substrate;
a gate located between the first base substrate and the first insulating layer;
an active layer located on one side of the first insulating layer away from the gate;
a pixel electrode located on one side of the first insulating layer away from the first base substrate;
a first electrode located on one side of both the active layer and the pixel electrode away from the first base substrate, wherein the first electrode is connected to the active layer and a surface of the first electrode close to the first base substrate is directly in contact with the pixel electrode, an end of the first electrode close to the pixel electrode being directly in contact with the pixel electrode;
a second electrode spaced apart from the first electrode, and connected to the active layer and a data line of the plurality of data lines;
a second insulating layer located on one side of the pixel electrode, the first electrode and the second electrode away from the first base substrate, the second insulating layer being in contact with the pixel electrode, and defining a first opening penetrating through second insulating layer, wherein an orthographic projection of the first opening on the first base substrate partially overlaps with an orthographic projection of the pixel electrode on the first base substrate, and partially overlaps with an orthographic projection of the first electrode on the first base substrate;
a connection electrode not integrated with the first electrode, and directly in contact with both the pixel electrode and the first electrode through the first opening, wherein the connection electrode is at least partially located in the first opening, a portion of a surface of the connection electrode close to the first base substrate is directly in contact with a surface of the first electrode away from the first base substrate, and another portion of the surface of the connection electrode close to the first base substrate is directly in contact with the pixel electrode; and
a common electrode located on one side of the second insulating layer away from the pixel electrode and spaced apart from the connection electrode, wherein the common electrode and the connection electrode are located in a same layer.
