    Abstract: The present disclosure provides an array substrate and a method of preparing the same. The array substrate includes a substrate, a gate, a gate insulation layer, an active layer, a crystallization layer, an oxide layer, a source/drain metal layer, and a passivation layer. After the crystallization layer is prepared, a mask plate is not removed and is used to protect an upper surface of the crystallization layer from oxidation reaction. Then, an oxide layer is formed on sidewalls of the crystallization layer and the active layer. The oxide layer is used to obstruct the source/drain metal layer from contacting the active layer. The source/drain metal layer is only in contact with the crystallization layer, thereby reducing a path of leakage current and achieving a purpose of reducing the leakage current.
