ABSTRACT:
A light-emitting device is disclosed capable of reducing the variation of an emission spectrum depending on an angle of viewing a light extraction surface. More particularly, a light-emitting device is disclosed capable of preventing impurities from dispersing from a light-emitting element into a thin film transistor as well as reducing the variation of an emission spectrum depending on an angle of viewing a light extraction surface. The disclosed light-emitting device comprises a substrate; a first insulating layer provided over the substrate; a transistor provided over the first insulating layer; and a second insulating layer having a first opening portion so that the transistor is covered and the substrate is exposed; wherein a light-emitting element is provided inside the first opening portion.
