OPTICAL-SEMICONDUCTOR-ELEMENT SEALING COMPOSITION, OPTICAL-SEMICONDUCTOR-ELEMENT SEALING MOLDED ARTICLE, OPTICAL-SEMICONDUCTOR-ELEMENT SEALING SHEET, OPTICAL SEMICONDUCTOR DEVICE, AND SEALED OPTICAL SEMICONDUCTOR ELEMENT

摘要

This optical-semiconductor-element sealing composition contains a sealing resin and optically diffusive organic particles. The absolute value of the difference between the index of refraction of the sealing resin and the index of refraction of the optically diffusive organic particles is 0.020-0.135, inclusive. The proportion of optically diffusive organic particles contained in the optical-semiconductor-element sealing composition in relation thereto is 1-10 mass%, inclusive. The optical-semiconductor-element sealing composition may be used in an optical semiconductor element.
