<P>PROBLEM TO BE SOLVED: To inhibit occurrence of variation in chromaticity among light-emitting devices in the case of mass producing the light-emitting devices. <P>SOLUTION: A manufacturing method of a light-emitting device including an LED element 3 radiating light of a predetermined first wavelength, and a wavelength conversion part containing phosphor particles radiating light of a second wavelength different from the first wavelength depending on irradiation of light of the first wavelength is disclosed. The manufacturing method comprises: (A) a first coating step of coating a phosphor coating liquid 40 containing the phosphor particles and an antisetting additive on the LED element 3; (B) a chromaticity measuring step of measuring chromaticity of light penetrating the phosphor coating liquid 40 coated on the LED element 3 by causing the LED element 3 to emit light; and (C) a second coating step of coating the phosphor coating liquid 40 on the LED element 3 again based on a measurement value of the chromaticity. <P>COPYRIGHT: (C)2012,JPO&INPIT |
