Patent ID: 8847414

Claim:
A resin for an encapsulation material, the resin comprising: a first polysiloxane including hydrogen bound to silicon (Si—H) at its terminal end, a second polysiloxane including an alkenyl group bound to silicon (Si—Vi) at its terminal end, and an adhesion promoter, wherein: a ratio (Si—H/Si—Vi) of hydrogen bound to silicon (Si—H) in the first polysiloxane to the alkenyl group bound to silicon (Si—Vi) in the second polysiloxane is about 1 to about 1.2; the resin being curable to form an encapsulation material that exhibits a light transmittance (T) of about 80% to about 100%, and the second polysiloxane is represented by the following Chemical Formula 2: (R 7 R 8 R 9 SiO 1/2 ) M2 (R 10 R 11 SiO 2/2 ) D2 (R 12 SiO 3/2 ) T2 (SiO 4/2 ) Q2 [Chemical Formula 2] wherein, in Chemical Formula 2, R 7 to R 12 are each independently a substituted or unsubstituted C1 to C30 alkyl group, a substituted or unsubstituted C3 to C30 cycloalkyl group, a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C7 to C30 arylalkyl group, a substituted or unsubstituted C1 to C30 heteroalkyl group, a substituted or unsubstituted C2 to C30 heterocycloalkyl group, a substituted or unsubstituted C2 to C30 alkenyl group, a substituted or unsubstituted C2 to C30 alkynyl group, a substituted or unsubstituted C1 to C30 alkoxy group, a substituted or unsubstituted C1 to C30 carbonyl group, a hydroxy group, or a combination thereof, provided that at least one of R 7 to R 12 includes the substituted or unsubstituted C2 to C30 alkenyl group, 0<M2<1,0<D2<1,0<T2<1,0≦Q2<1, and M2+D2+T2+Q2=1.
