摘要:
An epoxy resin composition for optical semiconductor element encapsulation includes an epoxy resin (Component (A)) mainly containing an epoxy compound represented by a specific structural formula (1), a curing agent (Component (B)), and at least one of an oxynitride phosphor and a nitride phosphor (Component (C)). Therefore, the phosphor component (C) is uniformly dispersed in the epoxy resin composition without segregation. Thus, the resin composition serves as an excellent optical semiconductor element encapsulation material which has an adequate light diffusion property and a high light transmittance and permits a reduction in internal stress. Therefore, a light emitting diode element encapsulated with the epoxy resin composition is capable of stably emitting light, and satisfactorily performs its functions.
