Abstract:
1. A semiconductor light emitting device comprising: a semiconductor layer having a first surface and a second surface on an opposite side to the first surface and including a light emitting layer; a first electrode provided in an emitting region of the semiconductor layer on a side of the second surface; a second electrode provided in a non-emitting region of the semiconductor layer on the side of the second surface; a first insulating film provided on the side of the second surface; a first interconnection layer provided on the first insulating film and connected to the first electrode; a second interconnection layer provided on the first insulating film and connected to the second electrode; a first metal pillar provided on the first interconnection layer and having an externally connectable end; a second metal pillar provided on the second interconnection layer and having an externally connectable end; a second insulating film provided in contact with a side surface of the first metal pillar and a side surface of the second metal pillar between the first metal pillar and the second metal pillar; and a fluorescent material layer provided on a side of the first surface and including (i) a plurality of fluorescent materials excitable by radiated light of the light emitting layer and radiating light of a different wavelength from the radiated light of the light emitting layer and (ii) a bonding material integrating the plurality of fluorescent materials and transmitting the radiated light of the light emitting layer and the radiated light of the fluorescent materials; wherein each of the first electrode, the first insulating film, the first interconnection layer, the second interconnection layer, and the second insulating film is transparent; and wherein the radiated light of the light emitting layer is extractable to (i) an outside of the fluorescent material layer on the side of the first surface and (ii) an outside of the second insulating film on the side of the second surface.
