An array substrate, a display panel, and a fabrication method of the array-substrate are provided. The array substrate comprises a first thin film transistor including a first metal oxide thin film transistor and disposed in a display region, a second thin film transistor including an amorphous silicon thin film transistor and disposed in a peripheral circuit region; and a third thin film transistor including a second metal oxide thin film transistor and disposed in the peripheral circuit region. A first insulating layer is disposed between a first metal oxide semiconductor layer and a first gate electrode, and a second insulating layer is disposed above the first gate electrode, a second gate electrode, and the first metal oxide semiconductor layer. The amorphous silicon semiconductor layer, a first source electrode, a first drain electrode, a second source electrode, a second drain electrode are disposed above the second insulating layer.
