Abstract
Provided is a light emitting device having a phosphor layer on a surface of a semiconductor light emitting element and achieving an even light distribution color, and a method of manufacturing the same. A method of manufacturing a light emitting device includes arranging a plurality of semiconductor light emitting elements spaced apart from each other on an expandable sheet, spraying a slurry containing a solvent, a thermosetting resin, and phosphor particles, onto an entire surface of the sheet having the arranged semiconductor light emitting elements to form a resin layer, pre-curing the resin layer, disuniting the resin layer formed on the surface of the semiconductor light emitting element from the resin layer formed on the sheet by expanding the sheet, and main curing the resin layer, which steps are performed in this order.
