Abstract: A display device includes a data conductive layer disposed on a substrate, a passivation layer disposed on the data conductive layer, a via layer disposed on the passivation layer, and a pixel electrode disposed on the via layer. The data conductive layer includes a data base layer, a data main metal layer disposed on the data base layer, a first data capping layer disposed on the data main metal layer, a second data capping layer disposed on the first data capping layer, and a third data capping layer disposed on the second data capping layer. The passivation layer and the via layer include a pad opening which exposes a portion of the data conductive layer in the pad area. The third data capping layer has a higher etch rate than the first and second data capping layers for a same etchant.
