1. A display device comprising:
a substrate;
a light emitting element on the substrate;
an inorganic layer on the light emitting element;
an insulating layer 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 on the second surface of the insulating layer, the first touch electrodes being arranged along a first direction;
second touch electrodes on the second surface of the insulating layer, the second touch electrodes being arranged along a second direction different from the first direction;
a first connecting electrode 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 between the inorganic layer and the first surface of the insulating layer;
the second connecting electrode comprises a first connect portion that directly contacts one of the two adjacent second touch electrodes of the second touch electrodes, a first protrusion protruded from the first connect portion in a third direction different from the first direction and the second direction, and a first line portion extended from the first connect portion;
a first portion of the first line portion is extended from the first connect portion in a fourth direction different from the first direction, the second direction and the third direction;
and
a thickness of the second connecting electrode is less than thicknesses of the two adjacent second touch electrodes of the second touch electrodes.
