Abstract
A light-emitting module includes: a plurality of light sources; and a lightguide plate including a plurality of light source placement sections, in each of which at least one light source is arranged, arrayed in a first direction and a second direction orthogonal to the first direction. The lightguide plate defines at least one first-A light control groove and at least one first-B light control groove that extend parallel to the second direction between a first light source placement section and a second light source placement section adjacent to the first light source placement section in the first direction, and at least one second-A light control groove and at least one second-B light control groove that extend parallel to the first direction between the first light source placement section and a third light source placement section adjacent to the first light source placement section in the second direction.
