Abstract
According to example embodiments, a light emitting device includes a transparent substrate, a transparent electrode on a transparent substrate, a transparent light extraction layer at least partially on the transparent electrode, a light emitting layer on the transparent electrode, and a reflective electrode on the light extraction layer and the light emitting layer. The light extraction layer and the light emitting layer may be alternately and repeatedly arranged between the transparent electrode and the reflective electrode.
