The invention provides a lead structure of a display panel, a preparation method thereof, and the display panel. The lead structure comprises a substrate, a first metal layer, an insulating layer and a second metal layer. According to the invention, the first metal layer is patterned, that is, the first metal layer is broken, so that the wiring area of the first metal layer is reduced, defects caused by particles during photoetching of the first metal layer are reduced, and the product yield is improved. And the gap part is filled with the insulating layer, so that short circuit of the second metal layer caused by poor etching of the first metal layer due to particulate matters is avoided. According to the invention, the second metal layer is connected with the first metal layer, that is, the whole wiring is realized by changing layers, so that the length of the wiring can be increased, and the resistance of the lead is reduced. 本发明提供一种显示面板的引线结构及其制备方法、显示面板，所述引线结构包括：基板、第一金属层、绝缘层以及第二金属层。本发明通过将第一金属层进行图案化设置，即将第一金
