Abstract
A light emitting diode chip including a substrate, a light emitting structure arranged on the substrate, the light emitting structure including an active layer arranged between a first conductive-type semiconductor layer and a second conductive-type semiconductor layer, and a distributed Bragg reflector to reflect light emitted from the light emitting structure. The distributed Bragg reflector has a reflectivity of at least 90% 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, and the distributed Bragg reflector has a reflectivity of at least 90% for light in a full wavelength range of 400 to 700 nm.
