Abstract: Disclosed herein are a light emitting diode chip and a light emitting diode package having a distributed Bragg reflector. The light emitting diode chip includes a substrate, a light emitting structure positioned on an upper portion of the substrate and including an active layer interposed between a first conductive-type semiconductor layer and a second conductive-type semiconductor layer, and a distributed Bragg reflector that reflects light emitted from the light emitting structure. The distributed Bragg reflector has a reflectivity of 90% or more for light of a first wavelength in a blue wavelength range, light of a second wavelength in a green wavelength range, and light of a third wavelength in a red wavelength range.
