Array substrate and display panel

The embodiment of the invention discloses an array substrate and a display panel. The array substrate comprises a substrate with a capacitance area and a non-capacitance area; a storage capacitor which is positioned in the capacitor area and comprises a first electrode layer, a first dielectric layer, a second electrode layer, a second dielectric layer and a third electrode layer which are sequentially stacked in the direction away from the substrate, wherein the third electrode layer is electrically connected with the first electrode layer through a first via hole and is insulated from the second electrode layer. The array substrate also comprises an insulating layer located in the non-capacitance area, and he thickness of the first dielectric layer and/or the second dielectric layer is smaller than the thickness of the insulating layer which is arranged on the same layer as the first dielectric layer and/or the second dielectric layer and is made of the same material as the first dielectric layer and the se
