Abstract

By using a composition for forming a light scattering composite, including surface-modified inorganic oxide particles surface-modified by a surface modification material having one or more functional groups selected from an alkenyl group, an H—Si group, and an alkoxy group, and an uncured matrix resin composition, in which an average dispersed particle diameter of the surface-modified inorganic oxide particles is 3 nm or more and 150 nm or less, and a content of the surface-modified inorganic oxide particles is 0.01% by mass or more and 15% by mass or less in a total solid content, it is possible to provide a white optical semiconductor light emitting device which has excellent light transmitting properties and scattering properties even if the content of light scattering particles is reduced, and as a result, further suppresses blue light irradiation and enhances a white light luminance, while enhancing color rendering properties.
