Patent ID: 10700133

Abstract:
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 a photocurable monomer and a photopolymerization initiator. The photocurable monomer includes a monomer containing no aromatic hydrocarbon group; and a monomer having two or more substituted or unsubstituted phenyl groups represented by Formula 1. The photocurable monomer includes about 5 wt % to about 45 wt % of the monomer having two or more substituted or unsubstituted phenyl groups and about 55 wt % to about 95 wt % of the monomer containing no aromatic hydrocarbon group.
