Abstract

Provided is a method of manufacturing a light emitting module, the method including: providing a light guiding plate having a first main surface serving as a lighting surface, and a second main surface opposite to the first main surface, the second main surface defining a recess thereon, preparing a light emitting element unit by attaching a wavelength conversion portion to a light emitting element having electrodes and a light emitting surface; providing a light diffusion portion at a bottom of the recess; depositing the light emitting element unit onto the light diffusion portion in the recess; and forming a terminal having an electrical conductivity on the electrodes of the light emitting element.
