Abstract
The present invention provides an addition-curable silicone composition comprising: (A) a linear organopolysiloxane having silicon atom-bonded aliphatic unsaturated groups and CF—(CF)—(CH)— groups; (B) an organopolysiloxane having silicon atom-bonded aliphatic unsaturated groups and CF—(CF)—(CH)— groups, and having a branched structure represented by SiOand RSiO; (C) an organosilicon compound having silicon atom-bonded hydrogen atoms and represented by the following general formula (1); and (D) a platinum group metal-based catalyst. There can be provided an addition-curable silicone composition that provides a cured product having low refractive index, high transparency, excellent light extraction efficiency, good rubber properties and strength properties, and no tack after curing, and in particular, has good transmittance of light with a wavelength of 400 nm at 25° C.
