  • Patent number: 11908870
    Abstract: A TFT array substrate includes a substrate layer and a metal layer disposed on the substrate layer. The metal layer includes a metal layer bridging structure having a first metal layer and a bridging second metal layer. An insulating layer is disposed between the first metal layer and the bridging second metal layer. The first metal layer includes two segments of a first segment and a second segment of the first metal layer, which are disposed at intervals. The first segment and the second segment of the first metal layer are connected by the bridging second metal layer. The TFT array substrate has a bending region adopting a new metal layer routing structure, and routing of the first metal layer in the bending region is prevented from passing through two holes of a filling layer (OILD), thereby effectively reducing the risk of subsequent breakage due to over-etching.
