Abstract: Embodiments provide a light emitting element that includes a base layer, a first electrode disposed on the base layer, a second electrode facing the first electrode, and functional layers disposed between the first electrode and the second electrode. The first electrode includes a first layer disposed on the base layer, and a second layer disposed on the first layer and including a reflective metal. Photonic crystal pore patterns, each spaced apart along a first direction and extending along a second direction crossing the first direction, are defined between the base layer and the first layer.
