Provided is a semiconductor light emitting diode having a textured structure formed on a substrate. In a method of manufacturing the semiconductor light emitting diode, a metal layer is formed on the substrate, and a metal oxide layer having holes is formed by anodizing the metal layer. The metal oxide layer itself can be used as a textured structure pattern, or the textured structure pattern can be formed by forming holes in the substrate or a material layer under the metal oxide layer corresponding to the holes of the metal oxide layer. The manufacture of the semiconductor light emitting diode is completed by sequentially forming a first semiconductor layer, an active layer, and a second semiconductor layer on the textured structure pattern.
