Abstract

A display apparatus according to an embodiment includes light-emitting devices and an encapsulation member, wherein the encapsulation member includes a light absorber including a hexagonal heterocycle containing two or more nitrogen atoms as ring-forming atoms, and first to third substituents substituted at the hexagonal heterocycle, the first to third substituents being different from one another, and thus can effectively block external light, thereby exhibiting improved reliability.
