Semiconductor light emitting device |
摘要 |
The invention provides an optical semiconductor device which comprises: an optical semiconductor element; a first resin layer encapsulating the optical semiconductor element and comprising a first resin and light-scattering particles; and one or more resin layers sequentially encapsulating the first resin layer and each comprising a resin having a lower refractive index than the first resin. In an embodiment where the optical semiconductor device has a plurality of resin layers over the first resin layer, the plurality of resin layers are disposed such that the refractive indexes of the constituting resins sequentially decrease toward the outermost resin layer. <IMAGE> |
