Abstract:
Provided is a light-emitting device with reduced in-plane luminance variation. The light-emitting device includes a main substrate, a plurality of light sources, a plurality of lenses, and one or more light reflection members. The main substrate includes a central part and a peripheral part that surrounds the central part. The plurality of light sources are each disposed on the central part of the main substrate. The plurality of lenses are disposed to correspond to the plurality of light sources respectively. The plurality of lenses apply optical effects to beams of light from the plurality of light sources respectively. One or more light reflection members are each disposed on the peripheral part. The light reflection members each have reflectance that is higher than the reflectance of the main substrate.
