There is provided a light-emitting device that exhibits superior luminance contribution rate of a light source while reducing in-plane luminance unevenness despite a simple configuration. The light-emitting device includes: a substrate on which one or more light sources are provided; and a reflective plate placed on the substrate. The reflective plate includes: an opening into which the light source is inserted; a sloped section that is sloped relative to the substrate while surrounding the opening, and has a first thickness; and a top surface section that is coupled to a top end of the sloped section, and has a second thickness. The first thickness is greater than the second thickness.
