Abstract

A light emitting device includes a plurality of light sources, a substrate, a partitioning member, a diffuser sheet, a plurality of first reflectors, and a second reflector. Each of the light sources includes a light emitting element and an encapsulant covering the light emitting element. The light sources are disposed on the substrate. The partitioning member surrounds the light sources and has a plurality of areas formed by walls having top parts. The walls include surfaces inclined with respect to an upper surface of the substrate to spread out from bottom parts toward the top parts. The diffuser sheet is provided over the partitioning member. The first reflectors are provided directly over the light sources, on an upper surface or a lower surface of the diffuser sheet. The second reflector is provided directly over the top parts, on the upper surface or the lower surface of the diffuser sheet.
