The light-emitting device includes a first substrate and a second substrate facing each other, a light-emitting element provided over the first substrate, a first sealant provided so as to surround the light-emitting element, and a second sealant provided so as to surround the first sealant. One of the first sealant and the second sealant is a glass layer and the other is a resin layer. A dry agent is provided in a first space surrounded by the first sealant, the second sealant, the first substrate, and the second substrate, or in the resin layer. The light-emitting element is included in a second space surrounded by the first sealant, the first substrate, and the second substrate.
