Partitioning member, planar light source, and liquid crystal display device

Abstract

A planar light source includes a substrate, a plurality of light sources arranged on the substrate, and at least one partitioning member disposed on the substrate. The at least one partitioning member includes: a plurality of first ridges extending in a first direction; a plurality of first wall parts, each first wall part having a predetermined height, at least two sides of each first wall part facing each other; a plurality of partitioned regions, each partitioned region being partitioned by the plurality of first ridges in a plan view, the plurality of partitioned regions arranged in a second direction intersecting the first direction; at least one first cut provided on a corresponding one of the plurality of first ridges; and at least one of the light sources arranged in a corresponding one of the plurality of partitioned regions.
