Abstract

A highly reliable light-emitting device which includes an organic EL element and is lightweight is provided. The light-emitting device includes a first organic resin layer; a first glass layer over the first organic resin layer; a light-emitting element over the first glass layer; a second glass layer over the light-emitting element; and a second organic resin layer over the second glass layer. The first organic resin layer and the first glass layer each have a property of transmitting visible light. The light-emitting element includes a first electrode having a property of transmitting visible light, a layer containing a light-emitting organic compound, and a second electrode stacked in this order from the first glass layer side.
