1. A touch display device comprising:
an encapsulation layer disposed on at least a portion of a non-active area and an active area, the encapsulation layer having an upper surface and including an inclined portion located in the non-active area;
a plurality of touch electrodes located on the encapsulation layer in the active area;
a plurality of touch routing lines located on the encapsulation layer in the non-active area, each of the plurality of touch routing lines being electrically coupled to at least one of the plurality of touch electrodes;
a touch planarization film disposed on the encapsulation layer, the touch planarization film having an upper surface and being located in at least a portion of an area overlapping the inclined portion of the encapsulation layer, and being located under the plurality of touch routing lines; and
first and second dams located in the non-active area, wherein the first dam is located between the second dam and the active area;
wherein the touch planarization film is disposed to not extend beyond an outermost boundary of the second dam,
wherein the upper surface of the touch planarization film is located at a level lower than the upper surface of the encapsulation layer, and
wherein the touch planarization film includes an inclined surface that overlaps a sidewall of the second dam that faces the first dam and does not overlap an upper surface of the second dam.
