PURPOSE: A light emitting device is provided to prevent a light extraction structure from being separated from a transparent electrode layer by forming an adhesion layer between the light extraction structures. CONSTITUTION: A light emitting structure(130) is located on a growth substrate(110). The light emitting structure includes a first conductive semiconductor layer(131), an active layer(132), and a second conductive semiconductor layer(133). A transparent electrode layer(140) is located on the light emitting structure. A plurality of light extraction structures are located on the transparent electrode layer. The light extraction structure includes zinc oxide. An adhesion layer(160) is located between the plurality of light extraction structures.
