Title:
TFT ARRAY SUBSTRATE AND DISPLAY PANEL THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/007980
Kind Code:
A1
Abstract:
The present invention provides a TFT array substrate, which comprises a substrate layer and a metal layer provided thereon. 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 provided 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 spaced apart, and the bridging second metal layer bridges the first section of the first metal layer and the second section of the first metal layer. The present invention provides a TFT array substrate. A new metal layer wiring structure design is used in a bending area of the TFT array substrate, thereby avoiding the situation in which the wiring of the first metal layer in the bending area passes through between two holes of an OILD filling layer, thereby effectively reducing the risk of subsequent disconnection caused by excessive etching.
