Provided are a method for manufacturing a thin-film transistor (TFT) substrate and a TFT substrate. The method for manufacturing a TFT substrate is capable of effectively protecting the surface of the inorganic insulating layer in the mark area and the mark peripheral area during performing dry etching on the metal layer by providing a protective layer between the inorganic insulating layer and the metal layer to reduce the surface damage of the inorganic insulating layer during dry etching, thereby effectively improving the recognition rate of the alignment mark by the CCD camera in the subsequent alignment process, improving the alignment detection accuracy, and avoiding subsequent alignment anomalies. In addition, it is not necessary to adjust the dry etching parameters of the metal layer, which indirectly reduces the process constraints of the dry etching process, avoids modification and calibration of the alignment CCD camera, and lowers production costs.
