Disclosed is a light emitting device including an active layer emitting light with a wavelength band of 200 nm to 405 nm, and a light-transmitting layer disposed on the active layer, the light-transmitting layer having a lower part facing the active layer, wherein at least one of side and upper parts of the light-transmitting layer has a surface-processed pattern portion.

Ultraviolet light emitting device

The embodiment relates to a light emitting device and a light emitting device package, wherein the light emitting device includes a first conduction type semiconductor layer, an active layer formed on the first conduction type semiconductor layer, and a second conduction type semiconductor layer formed on the active layer, wherein the active layer includes a quantum well layer and a quantum barrier layer, and a face direction lattice constant of the first conduction type semiconductor layer or the second conduction type semiconductor layer is greater than the face direction lattice constant of the quantum barrier layer and smaller than the face direction lattice constant of the quantum well layer.

Light emitting device and light emitting device package

Provided are a light emitting device, a light emitting device package, and a lighting system. The light emitting device includes a substrate, a light emitting structure comprising a first conductive type semiconductor layer, an active layer, and a second conductive type semiconductor layer, the light emitting structure being disposed on the substrate, a nonmetal pattern disposed between the substrate and the active layer, the nonmetal pattern being spaced from the substrate, and an air gap disposed on a side surface of the nonmetal pattern.
