Abstract
Disclosed are a light emitting device, a method of manufacturing the same and a light emitting device package. The light emitting device of the embodiment includes a light emitting structure including a first conductive semiconductor layer, a second conductive semiconductor layer and an active layer between the first and second conductive semiconductor layers; a fluorescent layer on the light emitting structure; and a light extracting structure on the fluorescent layer. The light extracting structure extracts light, which is generated in the light emitting structure and incident into an interfacial surface between the fluorescent layer and the light extracting structure, to an outside of the light emitting structure.
