Abstract:
A light emitting module includes: a plurality of light emitting elements each having a primary light emitting surface and a lateral surface; a plurality of wavelength conversion members arranged respectively on the primary light emitting surfaces of the plurality of light emitting elements; and a lightguide plate having a first primary surface and a second primary surface and arranged continuously on the plurality of wavelength conversion members so that the second primary surface faces the plurality of wavelength conversion members, wherein the lightguide plate includes a plurality of recessed portions located on the second primary surface, and a lateral surface of at least one of the plurality of wavelength conversion members is partially in contact with an inner lateral surface of at least one of the plurality of recessed portions.
