Abstract
A light-emitting module includes: a lightguide plate having a main surface and including a plurality of unit regions including at least one first unit region and a plurality of second unit regions, the lightguide plate including a plurality of first recesses in the main surface; a plurality of light sources provided at the main surface, each of the light sources being located in the first recess so as to correspond to one of the unit regions; and a light-transmitting member provided in the first recess of each of the unit regions. In the second unit regions, an optical axis of the light sources is coincident with a center of the first recess. In the first unit region, the optical axis of the light source is offset from the center of the first recess, and an upper surface of the light-transmitting member has a first receding part.
