1. A display device comprising:
a first substrate having a through hole area where a through hole is formed, a wiring area surrounding the through hole area, and a pixel area where a plurality of pixels are arranged to surround the wiring area;
first and second data lines on the first substrate to be adjacent to each other; and
a bridge electrode electrically connected to the second data line, and
wherein each of the plurality of pixels comprises:
an organic light-emitting diode (OLED) comprising a first electrode, a second electrode, and an organic light-emitting layer between the first electrode and the second electrode;
a driving transistor configured to provide a driving current to the OLED; and
a first transistor comprising a source electrode connected to the bridge electrode through a first contact hole, and a drain electrode connected to a source electrode of the driving transistor, and
wherein the first data line comprises a first metal layer in both the pixel area and the wiring area, and
the second data line comprises a second metal layer in both the pixel area and the wiring area, and
wherein a first insulating film is between the first metal layer and the second metal layer and between the bridge electrode and the second metal layer, and
wherein the second metal layer of the second data line is connected to the bridge electrode through a second contact hole penetrating the first insulating film, and
wherein the first metal layer of the first data line has a same material with the bridge electrode.
