Abstract:
1. A light emitting diode having a multi-cell structure including unit cells, comprising: a translucent substrate; a first semiconductor layer, an active layer and a second semiconductor layer sequentially formed on the translucent substrate; a plurality of holes formed to be spaced apart from each other by partially removing the region of the second semiconductor layer and the active layer; a first electrode being in contact with the first semiconductor layer through some holes of the plurality of holes, and formed so that the top surface thereof is exposed outside; a first protection film wrapping a side circumference of the first electrode to prevent a short between the first semiconductor and the second semiconductor; a second protection film formed on sides and bottom surfaces of holes, not having the first electrode, of the plurality of holes; a reflective layer or a current diffusion layer formed on the second protection film and the second semiconductor layer; and a second electrode formed on the reflective layer or the current diffusion layer.
