1. A display device comprising:
a substrate;
a display element layer disposed on a first surface of the substrate and including a light emitting element that emits light, the display element layer including:
a first contact electrode electrically connected to a first end of the light emitting element; and
a second contact electrode electrically connected to a second end of the light emitting element; and
a pixel circuit layer disposed on the display element layer and including a transistor electrically connected to the light emitting element, the pixel circuit layer including:
a reflective layer disposed on the display element layer and overlapping the light emitting element, wherein
one of the first contact electrode and the second contact electrode is electrically connected to the transistor, and
the reflective layer reflects the light emitted from the light emitting element toward a second surface of the substrate, wherein
the display element layer comprises a first electrode disposed between the first contact electrode and the substrate, and a second electrode disposed between the second contact electrode and the substrate, and
the first electrode and the second electrode are spaced apart from each other with the light emitting element disposed between the first electrode and the second electrode in a plan view, such that the first electrode and the second electrode reflect a reflected light provided from the reflective layer toward the second surface of the substrate.
