ABSTRACT:
The present invention relates to a method of manufacturing an LED device which emits light of multi-wavelengths. The invention also relates to a method of manufacturing LED devices which emit light of high quality from throughout the whole surface in a uniform manner. In particular, utilizing the manufacturing method of LED devices which emit light of multi-wavelengths makes it possible to produce LED devices of high quality in a simple and cost-efficient way, not by using adhesives, but by a sputtering or PLD method. In addition, since the characteristics of the desired emitted light can be controlled by controlling the amount and type of the phosphors during the manufacture of sputtering targets, high quality LED devices can be manufactured easily.
