Array substrate and method of making the same

Abstract

The invention provides an array substrate and a method of making the same, wherein the array substrate includes: a base substrate; a metal layer formed on the base substrate; a passivation layer formed on the base substrate and the metal layer; a planarization layer formed on the passivation layer; a contact hole formed by etching the planarization layer and the passivation layer on the metal layer, to make the metal layer at least partially exposed by the contact hole, wherein a hole wall of the contact hole at the passivation layer is coplanar with the hole wall at the planarization layer or the hole wall of the contact hole at the passivation layer and the hole wall at the planarization layer form an obtuse angle; a continuous pixel electrode layer formed on the planarization layer and the contact hole, wherein the pixel electrode layer is connected to the metal layer.
