Abstract: Disclosed are a light-emitting diode and a method for manufacturing the same. A light-emitting diode according to one aspect of the present invention includes: a first conductive clad layer; a light-scattering pattern configured, in the first conductive clad layer, having a refractive index different from that of the first conductive clad layer; an active layer located under the first conductive clad layer; a second conductive clad layer located under the active layer; a first electrode configured to be electrically connected to the first conductive clad layer; and a second electrode configured to be electrically connected to the second conductive clad layer. The light-scattering pattern can improve light extraction efficiency.
