Abstract:
There is provided a light-emitting device that makes is possible to emit light having less luminance unevenness. The light-emitting device includes: a light source substrate including a plurality of light sources; a first reflection member including a plurality of first apertures and a first overlap portion and located to overlap a portion of the light source substrate, each of the plurality of first apertures provided at a position corresponding to a relevant one of a plurality of first light sources, and the first overlap portion provided along an outer edge of the first reflection member; and a second reflection member including a plurality of second apertures and a second overlap portion and located to overlap another portion of the light source substrate, each of the plurality of second apertures provided at a position corresponding to a relevant one of a plurality of second light sources, and the second overlap portion provided along an outer edge of the second reflection member and overlapping the first overlap portion. The first reflection member and the second reflection member are provided at positions adjacent to each other in an in-plane direction, and are disposed to allow relative positions of the first reflection member and the second reflection member in the in-plane direction to be displaced within a range in which the first overlap portion and the second overlap portion overlap each other.
