Disclosed is an organic light emitting diode display apparatus including: a substrate; an organic light emitting diode disposed on the substrate; and an encapsulation layer encapsulating the organic light emitting diode. The encapsulation layer has a structure in which two or more inorganic layers and one or more organic layers are alternately stacked one above another, two adjacent inorganic layers at least partially contact each other, and the organic layers are formed of an encapsulating composition. The encapsulating composition includes: 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, the (B) silicon-based di(meth)acrylate being represented by Formula 1. |

1. An organic light emitting diode display apparatus, comprising: a substrate; an organic light emitting diode disposed on the substrate; and an encapsulation layer encapsulating the organic light emitting diode,
wherein the encapsulation layer has a structure in which two or more inorganic layers and one or more organic layers are alternately stacked one above another, two adjacent inorganic layers at least partially contacting each other, the organic layers being formed of an encapsulating composition, and wherein the encapsulating composition comprises 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, the (B) silicon-based di(meth)acrylate being represented by Formula 1: (where 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″)—* (* representing a binding site for an element, R′ being hydrogen or a substituted or unsubstituted C1 to C30 alkyl group, and R″ being 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—** (* representing a binding site for O in Formula 1, ** representing a binding site for Si in Formula 1, and R′ being a substituted or unsubstituted C1 to C30 alkylene group); X1, X2, X3, X4, X1 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″)—* (* representing a binding site for an element, and R′ and R″ being 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 from 0 to 30 on average). |
