Abstract
A light emitting module includes a light guiding plate being light-transmissive and having a first main surface being as a light exiting surface and a second main surface positioned opposite to the first main surface; a light emitting element disposed at the second main surface and configured to emit light toward the light guiding plate; an optical function part being greater in size than a light emitting surface of the light emitting element, the optical function part being disposed in the first main surface so as to correspond to an optical axis of the light emitting element; and a light-cutting scattering layer disposed on a first main surface side of the light guiding plate so as to correspond to the optical axis of the light emitting element. The light-cutting scattering layer covers the optical function part as seen in a plan view.
