PURPOSE: A light emitting device is provided to improve the light brightness of a single wavelength band which is emitted from a single light emitting device. CONSTITUTION: A conductive layer(110) is formed on a supporting member(115). A plurality of light emitting structure layers(120) is formed on the conductive layer to be vertically corresponded. Bonding layers(127,137) are formed on a partial region between the plurality of light emitting structure layers. Light transmissive support layers(125,135) are formed between at least one of the plurality of light emitting structure layers and the bonding layer. A protective layer(117) is formed at the circumference of a lower side of the light emitting structure layer. |
