Abstract
Disclosed are a thin-film transistor and a preparation method therefor, and a display substrate and a display panel. The thin-film transistor includes: a base substrate; an active layer located on the base substrate; and a source-drain electrode which is located on the side of the active layer facing away from the base substrate, and includes an electrode layer and a protective layer, where the material of the electrode layer includes a first metal element; the protective layer covers the surface of the side of the electrode layer facing away from the base substrate, and a side face of the electrode layer; and the material of the protective layer is an oxide of the first metal element.
