The present disclosure provides an array substrate and a liquid crystal display panel. The array substrate, including a display area and a non-display area, comprises: a substrate; a patterned first metal layer disposed on the substrate, wherein the first metal layer in the non-display area includes at least two first metal lines; an insulating layer disposed on the first metal layer; and a patterned second metal layer disposed on the insulating layer, wherein the second metal layer in the non-display area includes at least two second metal lines; wherein the first metal lines and the second metal lines surround the display area and connect to each other through a through-hole in the insulating layer, and at least one of the first metal lines or the second metal lines electrically connects to a ground line of the array substrate.
