1. A display device comprising:
a first electrode and a second electrode disposed on a substrate to be spaced apart from each other, each of the first electrode and the second electrode including an electrode base layer, a main electrode layer disposed on the electrode base layer, and an electrode upper layer on a portion of the main electrode layer;
a first insulating layer disposed on the first electrode and the second electrode;
light-emitting elements disposed on the first electrode and the second electrode on the first insulating layer;
a first connecting electrode disposed on the first electrode, the first connecting electrode being in contact with the light-emitting elements; and
a second connecting electrode disposed on the second electrode, the second connecting electrode being in contact with the light-emitting elements,
wherein
the first electrode includes a first part where the electrode upper layer is not disposed on the main electrode layer,
the second electrode includes a second part where the electrode upper layer is not disposed on the main electrode layer, and
the light-emitting elements are disposed on the first part and the second part of the first electrode and the second electrode,
the first insulating layer overlaps the electrode upper layer.
