Abstract
Provided are a curable composition, a light emitting diode, a liquid crystal display, and a lighting apparatus. The curable composition may have excellent processibility and workability, and excellent crack resistance, hardness, thermal resistance, transparency and adhesiveness after curing. The composition has neither whitening after being applied nor surface stickiness. The composition may be useful as an adhesive or encapsulating material of an optical semiconductor device such as an LED, a CCD or a photocoupler.
Claims18
A curable composition, comprising:
- a silicon resin which comprises a cyclic ether group and an aryl group and of which a molar ratio of the aryl group with respect to the silicon atoms is more than 0.5;
- and
- a silicon modified alicyclic acid anhydride curing agent which comprises an aryl group and of which a molar ratio of the aryl group with respect to the silicon atoms is more than 0.5.
