The invention provides a display panel, a preparation method thereof and a display device. The display panel comprises a first buffer layer, a first device layer and a second device layer, wherein the first device layer and the second device layer are arranged in the vertical direction of the first buffer layer; the first device layer comprises at least one first transistor structure, a first signal line layer and a connecting column, the first transistor structure comprises a first electrode layer and a second electrode layer, the first signal line layer, the second electrode layer and the connecting column are arranged on the same layer, and the first signal line layer is connected with the connecting column; the second device layer comprises at least one second transistor structure and a third signal line layer, the second transistor structure at least comprises a third electrode layer, the third electrode layer and the third signal line layer are arranged on the same layer, and the first device layer is provided with a through first via hole corresponding to the vertical direction of the connecting column. The third signal line layer is connected with the connecting columns through the first via holes. A transistor structure and a signal line of a circuit are arranged in a laminated mode, the wiring flexibility is improved, and meanwhile the manufacturing process is simplified.

The embodiment of the present application provides an array substrate and a display panel, and relates to the technical field of display, the array substrate comprises a display area and a non-display area surrounding at least part of the display area, the array substrate comprises a substrate, a signal trace and a plurality of electrostatic protection units, the signal trace is located on one side of the substrate, the signal trace is located in the non-display area, the signal trace comprises a straight line segment extending along a first direction and an oblique line segment connected with the straight line segment, and the oblique line segment and the straight line segment have a first included angle. The plurality of electrostatic protection units are located on one side of the substrate, the plurality of electrostatic protection units comprise a first electrostatic protection unit, the first electrostatic protection unit is located on a side of the oblique line segment away from the display area, and the included angle β1 between the extension direction of the first electrostatic protection unit and the extension direction of the oblique line segment is less than or equal to 30 DEG. The present application can reduce the space occupied by the first electrostatic protection unit in the frame, so that the frame of the array substrate can be narrower.
