PURPOSE: A curable composition is provided to have high refractivity before and after curing, maintaining moderate viscosity, have excellent processability, and workability, to have low moisture-permeability before and after curing, and to have excellent crack resistance, thermal resistance, impact resistance, adhesion, and hardness. CONSTITUTION: A curable composition comprises a mixture of a siloxane compound, and a silicon compound comprising hydrogen atoms combined to silicon atoms. The mixture comprises an alkenyl group combined with the silicon atom, comprises siloxane units in chemical formula 1: R^aR^bSiO_2/2, and chemical formula 2: R^cR^dSiO_2/2, and a siloxane oligomer compound in chemical formula 3 of which number of moles of the siloxane unit in chemical formula 1 is 1-5 times than number of moles of the siloxane unit in chemical formula 2. |
