Abstract: A display device includes a substrate having a display area and a pad area. A gate conductive layer disposed on the substrate includes a gate conductive metal layer and a gate capping layer. The gate conductive layer forms a gate electrode in the display area and a wire pad in the pad area that is exposed by a pad opening. An interlayer insulating film disposed on the gate conductive layer covers the gate electrode. A data conductive layer disposed on the interlayer insulating film in the display area includes source and drain electrodes. A passivation layer disposed on the data conductive layer covers the source and drain electrodes. A via layer is disposed on the passivation layer. A pixel electrode is disposed on the via layer. The pixel electrode is connected to the source electrode through a contact hole penetrating the via layer and the passivation layer.
