1. A display device comprising:
a first electrode and a second electrode disposed on a substrate, the first electrode and the second electrode being spaced apart from each other;
a first insulating layer disposed on the first electrode and the second electrode;
wall patterns disposed on the first insulating layer and overlapping the first electrode and the second electrode;
a second insulating layer disposed on the first insulating layer and overlapping the wall patterns;
light-emitting elements disposed directly on the second insulating layer and disposed between the wall patterns;
a bank layer disposed on the first insulating layer and surrounding an area including the light-emitting elements;
a first connecting electrode disposed on the first electrode and electrically contacting the light-emitting elements; and
a second connecting electrode disposed on the second electrode and electrically contacting the light-emitting elements, wherein
the first insulating layer includes an organic insulating material, and
the second insulating layer includes an inorganic insulating material,
wherein the first electrode and the second electrode are spaced apart from a trahsistor of a pixel driving circuit by an insulating layer therebetween in a thickness direction.
