Document Type and Number:
WIPO Patent Application WO/2024/039172
Kind Code:
A1
Abstract:
Provided are a composition for encapsulating an organic light-emitting device, and an organic light-emitting device display apparatus comprising organic layers formed therefrom, the composition comprising: (A) a radiation-curable multifunctional monomer; (B) a radiation-curable monofunctional monomer; (C) a silsesquioxane having one or two radiation-curable functional groups and a substituted or unsubstituted alkyl group; and (D) a photopolymerization initiator, wherein, on the basis of 100 parts by weight of the total amount of (A), (B), (C) and (D), the composition comprises 20-70 parts by weight of (A), 10-60 parts by weight of (B) and 5-50 parts by weight of (C).
