Abstract
A highly reliable flexible light-emitting device is provided. The light-emitting device includes a first flexible substrate, a second flexible substrate, a light-emitting element between the first flexible substrate and the second flexible substrate, a first bonding layer; and a second bonding layer in a frame shape surrounding the first bonding layer. The first bonding layer and the second bonding layer are between the second flexible substrate and the light-emitting element. The light-emitting element includes layer containing a light-emitting organic compound between the pair of electrodes. The second bonding layer has a higher gas barrier property than the first bonding layer.
