Array substrate and manufacturing method thereof, and display device

An array substrate, including a pixel electrode, a common electrode, and a thin film transistor, wherein

• the pixel electrode is arranged above the common electrode, and includes a first sub-electrode, a first connection part formed integrally with the first sub-electrode, a second sub-electrode, and a second connection part formed integrally with the second sub-electrode;
• the first sub-electrode and the second sub-electrode are insulated from each other and are disposed on different layers;
• and
• both the first connection part and the second connection part are connected to a drain of the thin film transistor,
• wherein a first passivation layer is disposed between the first sub-electrode and the second sub-electrode, and the first sub-electrode and the second sub-electrode are insulated from each other by the first passivation layer, and wherein the first sub-electrode is directly disposed on a second passivation layer, and the second sub-electrode is directly disposed on the first passivation layer, and
• wherein the first sub-electrode includes a first strip-shaped part and a first bending part connected to the first strip-shaped part, which are disposed on the second passivation layer;
• the first bending part and the first connection part are located at two ends of the first strip-shaped part, respectively;
• the second sub-electrode includes a second strip-shaped part and a second bending part connected to the second strip-shaped part, which are disposed on the first passivation layer;
• the second bending part and the second connection part are located at two ends of the second strip-shaped part, respectively;
• an orthogonal projection of the first bending part on the array substrate is at least partially overlapped with an orthogonal projection of the second bending part on the array substrate;
• an orthogonal projection of the first strip-shaped part and an orthogonal projection of the second strip-shaped part do not overlap with each other;
• and
• the first bending part and the second bending part are electrically connected to each other via the first strip-shaped part, the first connection part, the second strip-shaped part and the second connection part.
