<p>[Purpose] The purpose of the present invention is to provide a light-emitting device wherein it is possible to emit endface light having a high brightness from the endface on the entire periphery of the light-emitting device. [Configuration] A light transmission layer is formed so as to cover the planar light-emitting region of an organic EL light-emitting panel, and an opaque light reflection layer is disposed on the surface of the light transmission layer.</p>
