Abstract
The present invention relates to a thin film transistor array substrate with multiple chamfers and liquid crystal display device. A wiring structure is provided on the thin film transistor array substrate with multiple chamfers which is used for producing a plurality of thin film transistor arrays from a mother substrate, said wiring structure allows the chamfer quantity to be confirmed easily in the chamfer process for cutting off the corners of the terminal face after the cutting off process for taking out the respective thin film transistor arrays, meanwhile, the OLB pads is not easy to be peeled off from the substrate, and the probability that the OLB pads are peeled off can be reduced. On the thin film transistor array substrate with multiple chamfers, on the terminal face wiring up to the boundary of the OLB pad and the cut off line, the branch wiring is configured at both sides of said wiring based on the predetermined interval as the branch wiring for scale and OLB protection, when the chamfer is performed after the thin film transistor arrays are cut off from the mother substrate, the branch wiring for scale and OLB protection is used as a scale for confirming the dimension from the terminal face of the substrate to the OLB pad, and the OLB pad is not easy to be peeled off from the substrate.
