1. A touch display device, comprising:
a display panel including,
an inner area;
an edge area spaced from the inner area;
a step decline area between the inner area and the edge area;
a light emitting element located within the inner area, the light emitting element including an anode layer, a cathode layer, and an organic light emitting layer between the anode layer and the cathode layer;
an encapsulation layer on the cathode layer of the light emitting element;
a touch electrode including a touch electrode metal on the encapsulation layer; and
a touch circuit operatively connected to the display panel for sensing at least one of touch presence or touch location by using a touch sensing signal received from the touch electrode metals,
wherein the edge area includes a first compensation area that is a part of a region in the edge area,
wherein, in the inner area, the touch electrode metal has a first line width of a line for patterning the touch electrode metal in a mesh shape, and the encapsulation layer between the touch electrode metal and the cathode layer, has a first, substantially constant thickness,
wherein, in the first compensation area the touch electrode metal has a second line width of a line for patterning the touch electrode metal in a mesh shape, which is wider than the first line width, and
wherein the encapsulation layer thickness in the step decline are between the inner area and the first compensation area is reduce throughout the entire step decline area.
