This disclosure provides a curable silicone composition having a refractive index at 25° C. of 1.42 to 1.50. The composition comprises: (A) an organopolysiloxane having on average at least one alkenyl group with 2 to 12 carbon atoms and at least one aryl group with 6 to 12 carbon atoms in a molecule; (B) an organohydrogenpolysiloxane having on average at least one silicon-bonded hydrogen atom and at least one aryl group with 6 to 12 carbon atoms in a molecule; (C) a fumed silica; (D) a surfactant selected from a polyether-modified organopolysiloxane and a silicon-free polyether; and (E) a hydrosilylation reaction catalyst. The composition has a good film-forming property on a fluorine film, and cures to form a cured product with transparency and printability. Even if the cured product contacts with a transparent silicone adhesive (“Si-OCA”), it generally prevents migration of components, e.g., MQ resins, from Si-OCA to the cured product.
A curable silicone composition having a refractive index at 25° C. of 1.42 to 1.50 measured by means of an abbe refractometer at a wavelength of 589 nm, the composition comprising:
