LIGHT-EMITTING DIODE, METHOD FOR MANUFACTURING LIGHT-EMITTING DIODE, LIGHT-EMITTING DIODE LAMP AND ILLUMINATION DEVICE

摘要

A light-emitting diode with reduced light absorption, a method of manufacturing the same, a lamp and an illumination device are provided. A light-emitting diode (100) is provided with: a compound semiconductor layer (10) including a light-emitting layer (24) provided on a substrate (1); an ohmic contact electrode (7) provided between the substrate (1) and the compound semiconductor layer (10); an ohmic electrode (11) provided on the side of the compound semiconductor layer (10) opposite to the substrate (1); a surface electrode (12) including a branch section (12b) provided so as to cover the surface of the ohmic electrode (11) and a pad section (12a) coupled to the branch section (12b); and a current-blocking portion (13) provided between an under-pad light-emitting layer (24a) arranged in an area of the light-emitting layer (24) that overlaps the pad section (12a) in a planar view and a light-emitting layer (24) arranged in an area except the area that overlaps the pad section (12a) in a planar view, to prevent the current supplied to the under-pad light-emitting layer (24a).
