Abstract
A light emitting module includes: 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 that, in a schematic top view, is located between the sectioning groove and the light source placement part; and a light source disposed in the light source placement part. A refractive index of an inside of the light adjusting hole is lower than a refractive index of the light guide member. In the schematic top view, the light adjusting hole is positioned to intersect with a first straight line connecting a center of the light source and a farthest point in the sectioning groove, the farthest point being farthest from the center of the light source.
