ABSTRACT:
A curable composition comprising: component (A), which is an aliphatic organic compound including at least two carbon-carbon double bonds within one molecule, the at least two carbon-carbon double bonds having reactivity with an SiH group; component (B), which is a compound including at least two SiH groups within one molecule; and component (C), which is a hydrosilylation catalyst. The curable composition can be made into an optical material by being previously mixed so as to allow the carbon-carbon double bonds having reactivity with an SiH group to react with some or all of the SiH groups in the composition, thereby causing curing. There is provided a curable composition having a high heat-resistance, a low birefringence, a small coefficient of photoelasticity, a high optical transparency, and toughness; an optical material; a method for producing the same; and a liquid crystal display device incorporating the same.
