PURPOSE: A light emitting diode including a reflection layer is provided to improve the stability of a wavelength of output light and to maximally suppress a light loss from an LED. CONSTITUTION: An LED layer includes an N-type semiconductor layer (120), an active layer (130), and a P-type semiconductor layer (140). A current diffusion layer (150) is formed on the P-type semiconductor layer. A reflection layer (160) is formed on the current diffusion layer. The reflection layer is made of P-type metal to suppress a light loss due to total internal reflection. A plurality of reflection structures (161) are formed on the reflection layer. |
