(57) Abstract: In a thermosetting resin using a hydrosilylation reaction as a curing reaction, a composition for an optical material, in which cracks are suppressed in a thermal shock test, an optical material, and a liquid crystal display using the same. It is to provide a device, a light emitting diode and a manufacturing method thereof. SOLUTION: (A) an organic compound containing at least two allyloxy groups and / or metallyloxy groups in one molecule, (B) allyl glycidyl ether and / or methallyl glycidyl ether (α), and Is a compound obtainable by a hydrosilylation reaction with a linear and / or cyclic polyorganosiloxane (β) having at least three SiH groups, and A compound containing at least two SiH groups in the molecule, (C) A composition for optical materials containing a hydrosilylation catalyst as an essential component. |
