Abstract

Embodiments of the invention provide a display panel and a display apparatus. The display panel comprises a substrate, a first film layer, a first metal wire, and a bridge crossing metal wire, whereinthe first film layer is positioned on the substrate; the first film layer has an opening, and the opening comprises a bottom surface and a side wall; the upper surface, the side wall and the bottom surface, far from one side of the substrate, of the first film layer form a stage; the first metal wire is arranged on the upper surface of the first film layer and in the opening; the stage where thefirst metal wire is located is disconnected; the first end of the bridge crossing metal wire is electrically connected with a first trace wire through a via hole which runs through an insulating layer; and the second end of the bridge crossing metal wire is electrically connected with a second trace wire. By virtue of the abovementioned design, the stage where the first metal wire is located is disconnected, so that short circuit of the first metal wire is not caused by non-even photoresist thickness in the stage in the first metal wire manufacturing process through a patterning process, or bymetal residue in the stage after the patterning process is completed.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] In the process of making a display panel, some film layers will be made into a stepped shape, and then a metal layer will be made on the film layer, and the metal layer will be made into metal traces through a patterning process, wherein the metal traces They are not connected to each other. However, when the metal layer is patterned to form metal traces at the step by a patterning process, due to the uneven thickness of the photoresist at the step, the photoresist will remain where the photoresist is thicker, making The metal that needs to be etched away at the step is not etched away, so that the adjacent metal traces are in a connected state, thereby causing a short circuit of the metal traces. Contents of the invention [0003] Embodiments of the present invention provide a display panel and a dis...
