CURABLE RESIN COMPOSITION FOR REFLECTION OF LIGHT, AND OPTICAL SEMICONDUCTOR DEVICE

摘要

Provided is a curable resin composition which enables the production of a cured article having high light reflection performance, having excellent heat resistance and light resistance and high toughness, and rarely reduced in light reflection performance over time. A curable resin composition for reflecting light, characterized by comprising an alicyclic epoxy compound (A), rubber particles (B), a white pigment (C), a curing agent (D) and a curing-accelerating agent (E); or a curable resin composition for reflecting light, characterized by comprising an alicyclic epoxy compound (A), rubber particles (B), a white pigment (C) and a curing catalyst (F).
