Abstract

A light emitting module includes a light transmissive light guiding plate, a light adjustment portion, and a light emitting element. The light guiding plate has a first main surface serving as a light emitting surface which emits light outside, and a second main surface opposite to the first main surface. The second main surface is provided with a recess. The light adjustment portion is disposed in the recess of the light guiding plate. The light emitting element is bonded to the light adjustment portion. The light adjustment portion includes a wavelength conversion portion and a light diffusion portion. The light diffusion portion has a wavelength conversion portion side on which the wavelength conversion portion is bonded. The light diffusion portion is disposed on a bottom of the recess. The wavelength conversion portion is bonded to the light emitting element.
