Abstract:
A light emitting device includes a mounting board on which a plurality of light sources are disposed; a partitioning member surrounding the light sources and including a plurality of walls that include top parts and form a plurality of areas; a diffuser sheet provided above the partitioning member and supported directly or indirectly by at least one of the top parts; a plurality of first reflectors provided directly above the light sources and positioned on one of an upper surface and a lower surface of the diffuser sheet; a second reflector provided directly above the top parts and positioned on one of the upper surface and the lower surface of the diffuser sheet; and a wavelength conversion sheet positioned above the diffuser sheet. The first reflectors contain a light absorbing material that absorbs at least part of a wavelength of light from the light sources.
