Abstract: A display includes a plurality of sub pixels, a substrate, a light-emitting device, a pixel circuit, and an isolation portion. The light-emitting device, the pixel circuit, and the isolation portion are disposed on the substrate. The pixel circuit and the light-emitting device are coupled, and are located in the sub pixel. The pixel circuit includes a first transistor and a second transistor. An active layer of the first transistor includes polycrystalline silicon, and an active layer of the second transistor includes a semiconductor oxide. The isolation portion is configured at least to block hydrogen ions in the active layer of the first transistor from being diffused into the active layer of the second transistor.
