Light-emitting module

A light-emitting module comprising:

• a plurality of light sources;
• and
• a lightguide plate including:
• a first surface,
• a second surface opposite to the first surface, and
• a plurality of light source placement sections arranged in an array extending in a first direction and a second direction orthogonal to the first direction, wherein at least one of the plurality of light sources is arranged in each of the plurality of light source placement sections,
• wherein the plurality of light sources are located at a side of the second surface;
• wherein the plurality of light source placement sections include
• a first light source placement section,
• a second light source placement section that is adjacent to the first light source placement section in the first direction, and
• a third light source placement section that is adjacent to the first light source placement section in the second direction;
• wherein 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 the first light source placement section and the second light source placement section, 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 the third light source placement section;
• and
• wherein each of the at least one first-A light control groove and a corresponding one of the at least one second-A light control groove are connected to each other in a top plan view.
