Abstract:
1. A semiconductor light-emitting device, comprising: a first semiconductor layer having first conductivity; a second semiconductor layer having second conductivity different from the first conductivity; an active layer disposed between the first semiconductor layer and the second semiconductor layer and generating light by recombination of electrons and holes; a first pad electrode electrically connected to the second semiconductor layer; a branch electrode which extends from the first pad electrode; a light-transmitting conductive film which is formed under the branch electrode, wherein the branch electrode is disposed on the light-transmitting conductive film in a manner that the branch electrode is not disposed between the first pad electrode and the light-transmitting conductive film; an insulating body disposed between the branch electrode and the second semiconductor layer, wherein the branch electrode extends from the first pad electrode over the insulating body and wherein the branch electrode partially covers the insulating body; and wherein in a plan view the insulating body is arranged as plurality of islands along a length of the branch electrode outwardly and a thickness of the insulating body ranging from 3000 Å to 20000 Å.
