| 英文摘要 | A light emitting device includes at least one light emitting element including a plurality of semiconductor layers; and a light transmissive sealing member covering the at least one light emitting element. The light transmissive sealing member comprises a light transmissive sealing resin containing a silicone resin having a siloxane bond scaffold having methyl and phenyl groups as a principal ingredient. The light transmissive sealing resin has a refractive index in a range between 45 and 52, a durometer type D hardness at 25° C. specified by JIS K 6253 in a range between 20 and 70, and a DMA tan δ-based glass transition temperature (Tg) in a range between 20° C. and 70° C. |
