Abstract
Provided is an LED production method that can produce a great number of high-quality LEDs at low production cost. A binder-rich layer is formed on LEDs to increase the adhesiveness between the LEDs and a substrate; a phosphor layer or phosphor-rich layer is formed over the layer with a mask put on the layer; and the phosphor or a mixture of the phosphor and binder on the mask is recovered and reused.
