Abstract
A method for manufacturing a light-emitting device includes: providing an intermediate body having a first ultraviolet transmitting layer, a first adhesive layer, a plurality of first light emitting elements, a second adhesive layer, and a second ultraviolet transmitting layer; disposing on the second ultraviolet transmitting layer of the intermediate body, an ultraviolet shielding layer in a region corresponding to a part of the first light-emitting elements; performing first ultraviolet irradiation of irradiating the intermediate body with ultraviolet from a direction facing the ultraviolet shielding layer; performing second ultraviolet irradiation of irradiating the intermediate body with ultraviolet from a direction facing the first ultraviolet transmitting layer; and separating the part of the first light-emitting elements from the first adhesive layer along with the second adhesive layer.
