Abstract: A display device includes: a pixel circuit disposed on a base layer; an insulating layer disposed on the base layer covering the pixel circuit; a first electrode disposed on the insulating layer; a second electrode disposed on the insulating layer, the second electrode being spaced apart from the first electrode in a first direction; a light-emitting element disposed between the first electrode and the second electrode; a connection electrode connecting the first electrode and the light-emitting element and connecting the second electrode and the light-emitting element; a first auxiliary insulating layer disposed on the light-emitting element; and a second auxiliary insulating layer disposed on the first auxiliary insulating layer. The second auxiliary insulating layer includes a first insulating portion overlapped with the first auxiliary insulating layer, and a second insulating portion disposed outwardly from the first insulating portion and not overlapping the first auxiliary insulating layer.
