The present invention provides a thin-film-transistor (TFT) array panel and manufacturing method of the same. The TFT array panel comprises a flexible baseplate, a buffer layer, and a display-element layer. The buffer layer is disposed on the flexible baseplate, a stress-elimination portion is disposed on the buffer layer, the stress-elimination portion is used to eliminate a stress of the flexible baseplate; the display-element layer is disposed on the buffer layer. The present invention is able to decrease the stress of the flexible baseplate, to prevent too large of a stress of the flexible baseplate.
