Array substrate and preparation method therefor, and display apparatus

A manufacturing method for an array substrate, wherein the array substrate comprises a display area and a bezel area located on at least one side of the display area, the bezel area at least comprising a transition region and a circuit region, the circuit region being disposed on a side of the transition region away from the display area;

• the manufacturing method comprises:
• forming at least one first signal line and at least one second signal line in the display area, and forming at least one dummy signal line in the transition region, wherein both the at least one second signal line and the at least one dummy signal line extend along a second direction, the at least one first signal line extends along a first direction, and the first direction intersects with the second direction;
• an orthographic projection of at least one first signal line on the array substrate does not overlap with an orthographic projection of at least one dummy signal line on the array substrate.
