Abstract:
A light emitting module including: a light guide member including: an emission region defined by a sectioning groove, a light source placement part located in the emission region, and a light adjusting hole; and a light source disposed in the light source placement part. In the schematic top view: the light adjusting hole is not positioned on a first straight line connecting (i) a center of the light source and (ii) a point in the sectioning groove that is farthest from the center of the light source, and a first lateral face of the light adjusting hole has a first region, and a line normal to the first region is oblique to a second straight line connecting (i) the center of the light source and (ii) a point in the sectioning groove that is closest to the center of the light source.
