Title:
LIGHT-EMITTING DIODE HAVING IMPROVED LIGHT-EXTRACTION EFFICIENCY, AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2013/133593
Kind Code:
A1
Abstract:
Provided is a light-emitting diode. The light-emitting diode has a first electrically-conductive cladding layer. A light-scattering pattern having a refractive index different from that of the first electrically-conductive cladding layer is positioned in the first electrically-conductive cladding layer. An active layer is positioned below the first electrically-conductive cladding layer. A second electrically-conductive cladding layer is positioned below the active layer. An electrically connecting first electrode is positioned on the first electrically-conductive cladding layer. An electrically connecting second electrode is positioned on the second electrically-conductive cladding layer.
