Claim 10:
11. A method of manufacturing a surface light source module, the method comprising:
preparing a substrate;
mounting a plurality of light-emitting elements on the substrate;
accommodating, in a case, the substrate on which the light-emitting elements are mounted, and then forming, on the light-emitting elements, a first optical layer which covers the light-emitting elements and disperses light emitted from the light-emitting elements;
forming, on the first optical layer, a second optical layer configured to absorb the light emitted from the light-emitting elements and emit light of a different wavelength band from a wavelength of the absorbed light; and
cutting, in a set size, the substrate having the plurality of, integrally formed light-emitting elements mounted thereon, the first optical layer, and the second optical layer,
wherein a distance from an upper surface of the first optical layer to an upper surface of the second optical layer has a value less than a distance from an upper surface of the substrate to the upper surface of the first optical layer.
