Abstract:
A light-emitting device includes: a semiconductor layered structure; a conductive substrate disposed under the semiconductor layered structure; one or more upper electrodes each disposed on a portion of an upper surface of the semiconductor layered structure; a lower electrode disposed on a lower surface of the semiconductor layered structure; one or more metal members each having light reflectivity and disposed on the lower surface of the semiconductor layered structure in a region between (i) a region directly under a respective one of the one or more the upper electrodes and (ii) the region on which the lower electrode is disposed; one or more first insulating members each disposed on the lower surface of the semiconductor layered structure in the region directly under the respective one of the one or more the upper electrodes; and one or more second insulating members on a lower surface of the metal member.
