1. A display device comprising:
a substrate;
a light emitting element disposed on the substrate;
an inorganic layer disposed on the light emitting element;
an insulating layer disposed on the inorganic layer, the insulating layer including a first surface facing the inorganic layer and a second surface opposite to the first surface;
first touch electrodes disposed on the second surface of the insulating layer, the first touch electrodes arranged along a first direction;
second touch electrodes disposed on the second surface of the insulating layer, the second touch electrodes arranged along a second direction different from the first direction;
a first connecting electrode disposed on the second surface of the insulating layer, the first connecting electrode electrically connecting two adjacent first touch electrodes of the first touch electrodes in the first direction; and
a second connecting electrode electrically connecting two adjacent second touch electrodes of the second touch electrodes in the second direction,
wherein:
the second connecting electrode is disposed on a layer different from the second touch electrodes; and
a thickness of the second connecting electrode is less than thicknesses of the two adjacent second touch electrodes of the second touch electrodes, the second connecting electrode being disposed between the substrate and the second touch electrodes.
