CURABLE COMPOSITION, CURED PRODUCT AND PHOTO-SEMICONDUCTOR DEVICE

摘要

The present invention relates to a hardening composition comprising: polysiloxane (A) which has two or more alkenyl groups, aryl groups, and fluorine atoms in one molecule; polysiloxane (B) which has two or more alkenyl groups and aryl groups in one molecule and does not have a fluorine atom; hydrogen siloxane (C) which has two or more silicon atom-bonded hydrogen atoms in one molecule; and a catalyst (D) for hydrosilylation. By means of the hardening composition of the present invention, a hardened material can be formed so that a photo-semiconductor device having excellent luminance can be obtained. A photo-semiconductor device which has the hardened material produced by means of the hardening composition of the present invention as an encapsulating material has excellent luminance.
