Abstract
The present invention relates to a curable silicone composition comprising: (A) an organopolysiloxane having at least two alkenyl groups in a molecule; (B) an organopolysiloxane represented by a general formula; (C) an organopolysiloxane having at least two silicon-bonded hydrogen atoms in a molecule; (D) a phosphor; and (E) a hydrosilylation reaction catalyst, to a cured product obtained by curing said composition, and to an optical semiconductor device in which a light emitting element is sealed or coated with a cured product of the aforementioned composition. The curable silicone composition has excellent fluidity and cures to form a cured product in which phosphors are homogeneously dispersed and which has a high refractive index.
