Display panel, and array substrate and manufacturing thereof

A display panel, comprising:

• an array substrate, wherein the array substrate comprises:
• a backplane comprising a display area, a bonding area, and a transition area provided between the display area and the bonding area;
• a wiring layer provided on the backplane;
• a protective layer provided on a surface of the wiring layer away from the backplane, and covering the wiring layer in the display area and the bonding area, wherein a through-hole is provided in the protective layer in the bonding area;
• and
• a connection layer arranged in the display area, the transition area, and the bonding area, provided on a surface of the protective layer away from the backplane, and coupled to the wiring layer through the through-hole, wherein the protective layer is not provided in the transition area.

A method for manufacturing an array substrate, comprising:

• providing a backplane comprising a display area, a bonding area, and a transition area provided between the display area and the bonding area;
• forming a wiring layer on the backplane to cover the backplane;
• forming a protective layer on a surface of the wiring layer away from the backplane to cover the wiring layer in the display area and the bonding area;
• forming a through-hole in the protective layer in the bonding area;
• and
• forming a connection layer on a surface of the protective layer away from the backplane to be coupled to the wiring layer through the through-hole, wherein the connection layer is formed in the display area, the transition area, and the bonding area, and the protective layer is not provided in the transition area.
