Abstract
A light emitting device improves light extraction efficiency and may be individually driven in a light emitting device package and/or a light unit. The light emitting device may include first and second light emitting structures. The light emitting structure may include a first conductive first semiconductor layer, a first active layer under the first conductive first semiconductor layer, and a second conductive second semiconductor under the first active layer. The second light emitting structure may include a first conductive third semiconductor layer, a second active layer under the first conductive third semiconductor layer, and a second conductive fourth semiconductor layer under the second active layer.
