Abstract
An array substrate, a method of manufacturing thereof, and a display panel are provided. A source-drain layers are formed by a laminated metal layer. The laminated metal layer includes a first metal layer, a second metal layer, and a third metal layer that are stacked in order. By etching the stacked metal layer twice, a width of the third metal layer in the formed source-drain layer is less than or equal to a width of the second metal layer, thereby solving the problem of the undercutting of the laminated metal electrode in the array substrate of the prior art.
