Abstract: A method for transferring a light-emitting element from a first substrate to a second substrate includes: providing the light-emitting element fixed to a first surface of the first substrate via a release layer; and removing the release layer by irradiating the release layer with laser light from a side of the second surface, opposite the first surface, through the first substrate. An intensity distribution of the laser light on the first surface is, in the entire release layer, equal to or higher than a minimum intensity at which the release layer can be removed, and a maximum intensity of the intensity distribution is 150% or less of the minimum intensity.

Abstract: A light-emitting module includes a light-guiding plate having a light-extracting surface, a plurality of first light-emitting elements and a plurality of second light-emitting elements having a light-emission characteristic different from a light-emission characteristic of the first light-emitting elements, the first light-emitting elements and the second light-emitting elements being alternately mounted on a surface of the light-guiding plate opposite to the light-extracting surface, with electrodes facing a direction opposite to the light-extracting surface of the light-guiding plate, a light-reflective member covering each of the first light-emitting elements and each of the second light-emitting elements to expose electrodes of each of the first light-emitting elements and electrodes of each of the second light-emitting elements from a first surface, first wiring formed on the first surface to connect the electrodes of the first light-emitting elements, and second wiring formed on the first surface to connect the electrodes of the second light-emitting elements.
