Abstract
An array substrate includes a switching element, a signal transmission line, a passivation layer and a pixel electrode. The switching element is disposed on an insulating substrate. The signal transmission line is connected to the switching element and includes a barrier layer, a conductive line, and a copper nitride layer. The barrier layer is disposed on the insulating substrate. The conductive line is disposed on the barrier layer and includes copper or copper alloy. The copper nitride layer covers the conductive line. The passivation layer covers the switching element and the signal transmission line and has a contact hole through which a drain electrode of the switching element is partially exposed. The pixel electrode is disposed on the insulating substrate, and is connected to the drain electrode of the switching element through the contact hole.
