Abstract
Provided is a light emitting element, a light emitting device including the same, and fabrication methods of the light emitting element and light emitting device. The light emitting device comprises a substrate, a light emitting structure including a first conductive layer of a first conductivity type, a light emitting layer, and a second conductive layer of a second conductivity type which are sequentially stacked, a first electrode which is electrically connected with the first conductive layer; and a second electrode which is electrically connected with the second conductive layer and separated apart from the first electrode, wherein at least a part of the second electrode is connected from a top of the light emitting structure, through a sidewall of the light emitting structure, and to a sidewall of the substrate.
