Claim Text:
1. A method of manufacturing a light-emitting device which comprises a light-emitting element which emits light of a predetermined wavelength and a wavelength conversion portion which comprises a fluorescent substance which is excited by the light emitted from the light-emitting element so as to emit fluorescence of a wavelength different from the predetermined wavelength, the method comprising: forming a wavelength conversion portion on a light-emitting element, wherein the forming the wavelength conversion portion comprises: forming a fluorescent substance layer on the light-emitting element using a fluorescent substance dispersion liquid comprising a fluorescent substance and an anti-settlement agent; and applying a precursor solution comprising a binder for sealing the fluorescent substance and the anti-settlement agent on the fluorescent substance layer, wherein the fluorescent substance dispersion liquid has no organometallic compound to bind the fluorescent substance.
