Provided is a light-emitting device having an excellent light emission performance irrespective of its small thickness. The light-emitting device includes a base having a surface; one or more light sources that are provided on the surface of the base, and each have an optical axis; a reflective lens provided to interpose the light source between the reflective lens and the base; a reflective sheet that is provided to surround the light source along the surface of the base, and includes a first surface that makes a first angle relative to a plane that is substantially orthogonal to the optical axis to allow the first surface to be away also from the base as the first surface is away from the light source; and a light diffusion member provided to interpose the light source, the reflective lens, and the reflective sheet, between the light diffusion member and the base.
