Abstract
An encapsulating resin composition is provided, which gives a cured product having heat resistance, light resistance, and flexibility equivalent to those of silicone resins and having a refractive index of 1.57 or greater which is larger than that of epoxy resins. The encapsulating resin composition contains: a high refractive index acrylic-based or methacrylic-based monomer having a refractive index of 1.55 or greater; and a nonfunctional fluorene compound. In a preferred form, each of the high refractive index acrylic-based or methacrylic-based monomer and the nonfunctional fluorene compound has a 9,9-bisphenylfluorene skeleton.
