Classification: CPC G  H | IPC G

Claim 9:
10. A touch display device, comprising:
a plurality of touch electrodes located on an active area of a display panel, and disposed on an encapsulation layer disposed on the active area;
a transistor under the encapsulation layer, the transistor including a gate electrode and a source or drain electrode;
a plurality of touch link lines located outside of the active area, and electrically coupled to at least one of the plurality of touch electrodes;
a plurality of pad lines electrically coupled to each of the plurality of touch link lines; and
a plurality of touch pads electrically coupled to each of the plurality of pad lines,
wherein the plurality of touch pads include:
a plurality of first touch pads located on a first region, and electrically coupled to each of a plurality of first pad lines among the plurality of pad lines, disposed on a first layer that is a same layer as a layer where the first touch pad is disposed;
a plurality of second touch pads located on a second region located farther from the plurality of touch link lines than the first region, and electrically coupled to each of a plurality of second pad lines among the plurality of pad lines, the plurality of second pad lines each at least partially disposed on a layer different from a layer where the plurality of second touch pads are disposed and different from the layer where the plurality of first pad lines are disposed, and the plurality of second touch pads disposed on the same layer as the plurality of first touch pads; and
a plurality of third touch pads located on a third region located farther from the plurality of touch link lines than the second region, and electrically coupled to each of a plurality of third pad lines, among the plurality of pad lines, including a first portion disposed on a same layer as a layer where at least one of the plurality of first pad lines and the plurality of second pad lines is disposed and a second portion disposed on a different layer from a layer where the plurality of first pad lines and the plurality of second pad lines are disposed,
wherein the plurality of first touch pad are in a same layer as the gate electrode of the transistor, and

wherein the touch display device further comprises a first insulation layer between the first layer and the second layer.
