Abstract: A thin-film transistor (TFT) having a vertical structure and an electronic device are provided. The TFT having the vertical structure includes an insulating substrate and an active layer disposed on the insulating substrate. The active layer includes a first conductive part, an active section, and a second conductive part which are stacked. An orthographic projection of the first conductive part on the insulating substrate partly overlaps an orthographic projection of the second conductive part on the insulating substrate. Therefore, contamination ions may be prevented from entering the active section from the insulating substrate during manufacturing processes of the TFT. Thus, reliability of performance of the TFT may be improved.
