DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF

The disclosure provides a display device including a substrate, a first interconnection metal layer, a second interconnection metal layer, a passivation layer, a first through via, a second through via, a first electrode and a bonding pad. The substrate includes active and border regions. The first interconnection metal layer is disposed on the substrate and located in the active region. The second interconnection metal layer is disposed on the substrate and located in the border region. The passivation layer is disposed on the first and second interconnection metal layers. The first through via passes through the passivation layer and is electrically connected to the first interconnection metal layer. The second through via passes through the passivation layer and is electrically connected to the second interconnection metal layer. The first electrode is disposed on the first through via. The bonding pad is disposed on the second through via.
