Abstract
A thin film transistor (TFT) array substrate includes: a substrate; a first insulation layer on the substrate; a capacitor including a lower electrode on the first insulation layer, and an upper electrode arranged to overlap with the whole lower electrode and having an opening, and the upper electrode is insulated from the lower electrode by a second insulation layer; an inter-layer insulation film covering the capacitor; a node contact hole in the inter-layer insulation film and the second insulation layer, and within the opening; and a connection node on the inter-layer insulation film and electrically coupling the lower electrode and at least one TFT to each other through the node contact hole.
