The invention provides a TFT array base plate, which comprises a substrate layer and a metal layer disposed on the substrate layer, wherein the metal layer comprises a metal layer bridging structure;the metal layer bridging structure comprises 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 comprises a first section of the first metal layer and a second section of the first metal layer which are arranged at an interval; and the bridging second metal layer is in bridging with the first section of the first metal layer and the second section of the first metal layer. According to the TFT array base plate provided by the invention, the bending region adopts a new metal layer wiring structure design, the wiring of the first metal layer in the bending region is prevented from passing through the two holes of an OILD filling layer, and thus, the risk of subsequentdisconnection due to over-
