Abstract
A light-emitting device includes a circuit substrate including at least a pair of electrodes, an LED element electrically mounted on the circuit substrate, a phosphor plate disposed on an upper surface of the LED element, a diffuser plate disposed on an upper surface of the phosphor plate, and a white resin disposed on an upper surface of the circuit substrate and covering a peripheral side surface of the LED element, a peripheral side surface of the phosphor plate, and a peripheral side surface of the diffuser plate. The present invention makes it possible to obtain a planar light-emitting surface even with a plurality of LEDs, and also, a problem of color-ring occurrence caused by a phosphor may be less represented.
