摘要:
A light-emitting device has a structure in which a light-emitting element is placed on a wiring pattern, with the wiring pattern and an upper portion of the light-emitting element being connected with each other by a bonding wire, and has a feature in that a phosphor kneaded matter, obtained from a phosphor kneaded matter packaging container, is sealed on the wiring pattern and the light-emitting element by a sealing resin. With this structure, it becomes possible to emit white light with high efficiency and consequently to obtain white light that is remarkably superior in color reproducibility (NTSC ratio).
