A display device is discussed. The display device according to an embodiment includes a substrate, a display region disposed over the substrate and including a plurality of subpixels, and a data pad part disposed in regions other than the display region. The data pad part includes a data signal line extended from the display region, an insulating film disposed on the data signal line and insulating the data signal line, a data pad electrode disposed on the insulating film and connected to the data signal line through the via hole, and an insulating pattern configured to cover the via hole. The data pad electrode can include at least one electrode hole.
