AI Technical Summary
Technical Problem
During substrate cutting, adjacent metal line layers are prone to abnormal short circuits of different types, leading to display abnormalities.
Method used
By optimizing the routing layout and patterning, the cutting lines are placed in areas where the two different types of traces do not overlap, thus avoiding cutting to different types of traces at the same time.
Benefits of technology
This reduces the risk of abnormal short circuits caused by cutting, and improves the product yield and display effect of the display backplane.

Abstract
Embodiments of the present application disclose a display backplane and a display device; the display backplane comprises a wiring layer, the wiring layer comprises a plurality of first type wirings arranged along a first direction and a plurality of second type wirings arranged along a second direction, at least one first type wiring comprises a first end surface flush with an edge of the display backplane, at least one second type wiring comprises a second end surface flush with the edge of the display backplane, and the first end surface and the second end surface are arranged non-overlappingly in a top view direction of the display backplane; the present application optimizes the arrangement and patterning of the wirings, sets the cutting line in the area where the two different types of wirings do not overlap, avoids cutting into different types of wirings at the same time, thereby reducing the risk of abnormal short circuit of different types of lines caused by cutting, improving the product yield of the display backplane, and improving the display effect.
