Abstract
An embodiment of the present application discloses an array substrate and a manufacturing method thereof. The array substrate includes an underlay, an active layer, a gate electrode insulation layer, and a metal layer. A first through hole, second through holes, third through holes, and a fourth through hole are defined in the gate electrode insulation layer. The second through holes and third through holes are arranged at intervals such that partial regions of the active layer are shielded by the gate electrode insulation layer to prevent them from corrosion of an etching solution to guarantee a normal electrical connection of the active layer and a source electrode and a drain electrode and improve a yield rate of the array substrate.
