Array substrate and mother-board for array substrates

A motherboard comprising a plurality of array substrates of arranged in an array, wherein each of the plurality of array substrates comprises a display area and a non-display area on a periphery of the display area, the non-display area is provided with an interface area, and the plurality of array substrates comprises:

• a plurality of signal lines, extending in the display area and leading out to the non-display area;
• a plurality of pads located in the interface area, wherein each of the plurality of pads is connected with a corresponding one of the plurality of signal lines;
• and
• a short-circuiting component located in the non-display area, wherein the short-circuiting component is connected with the plurality of pads, the plurality of signal lines connected with the plurality of pads are short-circuited, the short-circuiting component includes a semiconductor structure and a first metal structure, and an orthographic projection of the semiconductor structure in a thickness direction of the array substrate coincides with an orthographic projection of the first metal structure in the thickness direction of the array substrate, and the semiconductor structure and the first metal structure have the same structure in a plane dimension perpendicular to the thickness direction of the array substrate.
