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,
the reflective layer reflects the light emitted from the light emitting element toward a second surface of the substrate, and
the display element layer comprises:
banks disposed on and above the substrate and spaced apart from each other with the light emitting element disposed between the banks, each bank extending above the light emitting element disposed; and
a first electrode and a second electrode disposed on the banks and spaced apart from each other with the light emitting element disposed between the first electrode and the second electrode.
