Abstract

It is an object to provide a flexible light-emitting device with long lifetime in a simple way and to provide an inexpensive electronic device with long lifetime using the flexible light-emitting device. A flexible light-emitting device is provided, which includes a substrate having flexibility and a light-transmitting property with respect to visible light; a first adhesive layer over the substrate; an insulating film containing nitrogen and silicon over the first adhesive layer; a light-emitting element including a first electrode, a second electrode facing the first electrode, and an EL layer between the first electrode and the second electrode; a second adhesive layer over the second electrode; and a metal substrate over the second adhesive layer, wherein the thickness of the metal substrate is 10 μm to 200 μm inclusive. Further, an electronic device using the flexible light-emitting device is provided.
