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.

Abstract: A display device includes pixel circuits disposed in a display area and a driving circuit disposed in the peripheral area. The driving circuit includes a first transistor and each pixel circuit includes a second transistor. The first transistor includes a first active pattern disposed on the substrate, a first gate insulation layer having a first outer portion disposed on the first active pattern, and a first gate electrode disposed on the first gate insulation layer. The second transistor includes a second active pattern disposed on the substrate, a second gate insulation layer having a second outer portion disposed on the second active pattern, and a second gate electrode disposed on the second gate insulation layer. The first outer portion doesn't overlap the first gate electrode and has a first width. The second outer portion doesn't overlap the second gate electrode and has a second width smaller than the first width.
