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.
一种实施例的显示装置包括发光装置和封装件,其中封装件包括一个吸光体,该吸光体包括一个六元杂环,其中含有两个或更多氮原子作为环形成原子,并且在该六元杂环上取代第一到第三取代基,第一到第三取代基彼此不同,因此可以有效地阻挡外部光线,从而展现出更高的可靠性。
