Beschreibung
Zusammenfassung:	A planar light source has a plurality of light sources, a substrate, and a partitioning member. The partitioning member includes a first member provided with first partitioned parts each having a first bottom part and first oblique parts surrounding the first bottom part that are arranged on the substrate in a matrix, and a second member provided with second partitioned parts each having a second bottom part and second oblique parts surrounding the second bottom part that are arranged on the substrate in a matrix. The first member further has first outer oblique parts overlapping the second oblique parts located along the outer edge of the second member on the first member side. The first bottom parts and the second bottom parts each have a light source disposition opening, and the light sources are individually disposed on the substrate exposed in the light source disposition openings.
