Abstract:
A method for manufacturing a light emitting device includes providing a wafer including a substrate, a light emitting structure layer and a plurality of electrodes, forming a phosphor layer so as to cover a surface of the wafer on a side of the substrate, dividing the wafer and the phosphor layer so as to form a plurality of light emitting elements, measuring a luminescent chromaticity of the plurality of light emitting elements so as to classify into a first light emitting element having a luminescent chromaticity within a required chromaticity range and a second light emitting element having a luminescent chromaticity outside the required chromaticity range, and forming a second light emitting device that includes the plurality ones of the second light emitting element and the luminescent chromaticity within the required chromaticity range by using the second light emitting element.
