In an embodiment, the scan line 21, the data line 22, the first power line 23 and the second power line 34 are arranged on the same layer, and are made of the same material, and all the traces are not cross-wired in the display panel, so that the scan line, the data line 22, the first power line 23 and the second power line can be prepared by the same metal layer, the thickness of the display panel is reduced, the manufacturing process is simplified, and the production cost is reduced.
In an embodiment, as shown in fig. 7, the display panel 100 of the present embodiment may include a substrate 41, a first metal layer 42, a first insulating layer 43, an anode 44, and further may include a film layer such as an organic light emitting layer and a cathode.
