Abstract: Embodiments may be directed to a display panel includes a base substrate including a display region having a plurality of pixels and a non-display region adjacent to the display region, a connecting line in the non-display region and including at least a first input pad, a second input pad, and an output pad, and an insulating layer on the connecting line. The insulating layer includes at least one first contact hole exposing at least a portion of the first input pad, at least one second contact hole exposing at least a portion of the second input pad, and at least one third contact hole between the first contact hole and the second contact hole. A first contact electrode, a second contact electrode, and a dummy contact electrode are disposed at the first, second and third contact holes, respectively.
