Abstract:
A light emitting device manufacturing method includes: disposing n pieces of light emitting elements in m rows on a substrate block, where an interval between a kth light emitting element from one end of rows and a (k+1)th light emitting element has a first distance; disposing a phosphor member on the light emitting elements; disposing a frame member to surround the light emitting elements; disposing a cover member in each area surrounded by the frame member to cover lateral surfaces of the light emitting elements and the phosphor members while forming recesses at an upper surface between the kth light emitting elements and the (k+1)th light emitting elements apart by the first distance; disposing a light shielding member in each recess; and cutting the light shielding members, the cover members, and the substrate block between the light emitting elements that are apart by the first distance.
