Organic light emitting device encapsulating composition, and organic light emitting device display apparatus manufactured using same

A composition for encapsulation of an organic light emitting diode, the composition comprising:

• about 10 wt % to about 70 wt % of (A) a non-silicon-based di(meth)acrylate;
• about 20 wt % to about 70 wt % of (B) a silicon-based di(meth)acrylate;
• about 5 wt % to about 40 wt % of (C) a mono(meth)acrylate;
• and
• about 1 wt % to about 10 wt % of (D) an initiator, based on the total weight of (A), (B), (C) and (D),
• wherein the (B) silicon-based di(meth)acrylate is represented by Formula 1:
• wherein, in Formula 1,
• R1 and R2 are each independently a single bond, a substituted or unsubstituted C1 to C20 alkylene group, a substituted or unsubstituted C1 to C30 alkylene ether group, *—N(R′)—(R″)—* (* represents a binding site for an element, R′ is hydrogen or a substituted or unsubstituted C1 to C30 alkyl group, and R″ is a substituted or unsubstituted C1 to C20 alkylene group), a substituted or unsubstituted C6 to C30 arylene group, a substituted or unsubstituted C7 to C30 arylalkylene group, or *—(R′)—O—** (* represents a binding site for O in Formula 1, ** represents a binding site for Si in Formula 1, and R′ is a substituted or unsubstituted C1 to C30 alkylene group);
• X1, X2, X3, X4, X5 and X6 are each independently hydrogen, a hydroxyl group, a halogen, a cyano group, a substituted or unsubstituted C1 to C30 alkyl group, a substituted or unsubstituted C1 to C30 heterocycloalkyl group, a substituted or unsubstituted C3 to C30 cycloalkyl group, a substituted or unsubstituted C1 to C30 alkyl ether group, *—N(R′)—(R″)—* (* represents a binding site for an element, and R′ and R″ are each independently hydrogen or a substituted or unsubstituted C1 to C30 alkyl group), a substituted or unsubstituted C1 to C30 alkyl sulfide group, a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C2 to C30 heteroaryl group, or a substituted or unsubstituted C7 to C30 arylalkyl group;
• at least one of X1, X2, X3, X4, X5 and X6 is a substituted or unsubstituted C6 to C30 aryl group, or a substituted or unsubstituted C2 to C30 heteroaryl group;
• R3 and R4 are each independently hydrogen or a methyl group;
• and
• n is an integer from 0 to 30, or ranges on average from 0 to 30.
