Abstract

A light-emitting device capable of long-time display in a bent state is provided. A light-emitting device that can be repeatedly bent with a small radius of curvature is provided. The flexible light-emitting device includes a light-emitting element, a first inorganic insulating layer, a second inorganic insulating layer, and a first organic insulating layer. The first organic insulating layer is positioned over the first inorganic insulating layer. The light-emitting element is positioned over the first inorganic insulating layer with the first organic insulating layer therebetween. The second inorganic insulating layer is positioned over the light-emitting element. An end portion of the first inorganic insulating layer and an end portion of the second inorganic insulating layer are each positioned inward from an end portion of the first organic insulating layer. The end portion of the first organic insulating layer is exposed on a side surface of the light-emitting device. The first inorganic insulating layer and the second inorganic insulating layer are preferably in contact with each other outside an end portion of the light-emitting element.
