Abstract: A display device includes a pixel circuit, a first insulating layer covering the pixel circuit, a first electrode disposed on the first insulating layer, a second electrode disposed on the first insulating layer and spaced apart from the first electrode in a first direction, and a light emitting element electrically connected to the first electrode and the second electrode and disposed between the first electrode and the second electrode. A recess is provided in a first region of the first insulating layer between the first electrode and the second electrode when viewed in a plan view, and a width of the recess in the first direction is greater than a length of the light emitting element in the first direction. The first electrode and the second electrode do not overlap the recess when viewed in a plan view.
