The utility model provides an active matrix organic electroluminescence display part and a display device. The active matrix organic electroluminescence display part comprises a substrate and a plurality of pixel units formed on the substrate. The pixel units comprise driving regions and light emitting regions, and at least two film transistors are arranged in each driving region. Organic electroluminescence structures driven by the film transistors are arranged in the light emitting regions. The film transistors are of a top grid structure and comprise active layers, sources, drains, passivation layers and grids, wherein the active layers are formed on the substrate, the sources and the drains are formed on the sides, far away from the substrate, of the active layers, the passivation layers are formed on the sides, far away from the active layers, of the sources and the drains and cover the whole driving regions and the whole light emitting regions, and the grids are formed on the sides, away from the source
