发明名称 Light-emitting device and manufacturing method thereof
摘要 A light-emitting device of the present invention includes: a light-emitting element; and a phosphor layer containing phosphors that absorb light from the light-emitting element and wavelength-convert the absorbed light to emit light. The phosphor layer has a structure in which the phosphors are disposed on an applied adhesive with a thickness equal to or less than an average particle size of the phosphors. A thickness of the phosphor layer is equal to or less than five times the average particle size of the phosphors, and an occupancy ratio of the phosphors in the phosphor layer is 50% or more. Further, the phosphors disposed on the adhesive has an adjusted particle size.
