1. A display apparatus comprising:
a substrate;
a first touch electrode line formed in a touch sensor metal layer on the substrate, the first touch electrode line having a first touch electrode and a second touch electrode; and
a second touch electrode line formed in the touch sensor metal layer, the second touch electrode line having a third touch electrode and a fourth touch electrode, wherein the third touch electrode and the fourth touch electrode are integrally formed and coupled to each other at a touch sensor connection portion in the touch sensor metal layer,
a bridge metal layer having a first bridge metal connection pattern electrically connecting the first touch electrode and the second touch electrode;
a touch-interlayer insulating layer disposed between the touch sensor metal layer and the bridge metal layer,
wherein the touch sensor connection portion where the third touch electrode and the fourth touch electrode connect overlaps and is aligned with the first bridge metal connection pattern,
a first bridge metal electrode extending from the first touch electrode in the touch sensor metal layer to the bridge metal layer; and
a second bridge metal electrode extending from the second touch electrode in the touch sensor metal layer to the bridge metal layer,
wherein the first touch electrode has a two-layer structure comprising the touch sensor metal layer forming a first touch sensor metal electrode and the bridge metal layer forming the first bridge metal electrode,
wherein the second touch electrode has a two-layer structure comprising the touch sensor metal layer forming a second touch sensor metal electrode and the bridge metal layer forming the second bridge metal electrode.
