Abstract
A display panel and fabrication method, and a display device are provided. The display panel includes a substrate, an array layer disposed on the substrate, and a light-emitting device disposed on a side of the array layer facing away from the substrate. The array layer includes a thin film transistor, and the thin film transistor includes a ring-shaped active layer, a ring-shaped gate electrode isolatedly overlapped with a channel region of the ring-shaped active layer, and a ring-shaped first end corresponding to and connected to the ring-shaped active layer. The ring-shaped first end is one of a source electrode and a drain electrode of the thin film transistor. The light-emitting device includes a first electrode, and the first electrode is connected to the ring-shaped first end, and the first electrode is a ring-shaped electrode.
