Abstract: A display device includes a lower metal layer disposed on a surface of a substrate and including a first opening overlapping a rear emission pixel in a plan view; a first electrode and a second electrode disposed in each of the rear emission pixel and a front emission pixel, the first electrode and the second electrode being spaced apart from each other on the lower metal layer; first light emitting elements disposed between the first electrode and the second electrode disposed in the rear emission pixel; second light emitting elements disposed between the first electrode and the second electrode disposed in the front emission pixel; and a reflective layer disposed on the first light emitting elements and overlapping the rear emission pixel in a plan view, the reflective layer overlaps at least one of the first light emitting elements in a plan view.
