Disclosed herein is a flip-chip type nitride semiconductor light emitting diode. The light emitting diode comprises an n-type nitride semiconductor layer formed on a transparent substrate and having a substantially rectangular upper surface, an n-side electrode which comprises at least one bonding pad adjacent to at least one corner of the upper surface of the n-type nitride semiconductor layer, extended electrodes formed in a band from the bonding pad along four sides of the upper surface of the n-type nitride semiconductor layer and one or more fingers extended in a diagonal direction of the upper surface from the bonding pad and/or the extended electrodes, an active layer and a p-type nitride semiconductor layer sequentially stacked on a region of the n-type nitride semiconductor layer where the n-side electrode is not formed, and a highly reflective ohmic contact layer formed on the p-type nitride semiconductor layer.
