1. An array substrate comprising a semiconductor layer, wherein the semiconductor layer comprises a structure for enhancing electron mobility of the semiconductor layer;

  • the structure for improving the electron mobility of the semiconductor layer comprises a polycrystalline silicon layer;

    the semiconductor layer further comprises an amorphous silicon layer surrounding the polycrystalline silicon layer;

    the semiconductor device further comprises a conductor layer, wherein the conductor layer comprises a first conductor layer and a second conductor layer, the first conductor layer is located on the semiconductor layer, the second conductor layer is located on the first conductor layer, and phosphine content in the first conductor layer and phosphine content in the second conductor layer are different;

    the amorphous silicon layer comprises a first amorphous silicon layer and a second amorphous silicon layer, and the first amorphous silicon layer and the polycrystalline silicon layer are arranged on the same layer and surround the polycrystalline silicon layer;

    the second amorphous silicon layer is only positioned on the first amorphous silicon layer;

    the protective layer is positioned above the polycrystalline silicon layer and covers the polycrystalline silicon layer.
