THERMOSETTING LIQUID COMPOSITION FOR ENCAPSULANT IN ORGANIC LIGHT-EMITTING DEVICE
20230054116 · 2023-02-23 ·

Disclosed is a liquid composition for an encapsulant of an organic light-emitting device. The liquid composition is free of a physical and chemical hygroscopic agent (getter) but includes a binder material having high hygroscopicity including an aliphatic 4-functionalized epoxy-based compound. Thus, the liquid composition for the encapsulant may be rapidly cured at low temperature and may secure excellent storage stability under a high temperature environment.
