Abstract
An optical semiconductor device that combines low gas permeability and high reliability. A curable silicone resin composition comprising: (A) an alkenyl group-containing organopolysiloxane comprising an organopolysiloxane represented by an average composition formula (1) and containing at least two alkenyl groups per molecule:(RSiO)(RSiO)(RRSiO)  (1)wherein Rrepresents an alkyl group, Rrepresents an aryl group, Rrepresents an alkenyl group, and Rrepresents an alkyl group or an aryl group,
