Abstract
A thin-film transistor (TFT) array substrate includes a first conductive layer of a TFT, a second conductive layer that partially overlaps the first conductive layer, a through hole in a layer between the first and second conductive layers, a node contact hole integrally formed to include a first contact hole in the first conductive layer and a second contact hole in the second conductive layer such that the first contact hole is continuous with the second contact hole and is not separated from the second contact hole by an insulation layer, and a connection node that is in another layer different from the first conductive layer and the second conductive layer. The connection node is connected to the first and second conductive layers through the through hole and the node contact hole.
