PURPOSE: A semiconductor light emitting device is provided to improve the light extraction efficiency and to drive in the AC power source by optimizing an electrode arranging structure. CONSTITUTION: A plurality of light emitting structures is arranged on a substrate and comprises a first electrical conduction semiconductor layer(103), an active layer(102), a second electrical conduction semiconductor layer(101), and a first and a second electrical connection parts(104,107) which are respectively connected with the first electrical conduction semiconductor layer and the second electrical conduction semiconductor layer. The plurality of light emitting structures is each other electrically connected in order to be driven with the AC power source applied from outside. The first electrical conduction semiconductor layer, the active layer, the second electrical conduction semiconductor layer are formed on the first electrical connection part. The second electrical connection part penetrates the first electrical connection part and the first electrical conduction semiconductor layer and connects with the second electrical conduction semiconductor layer. The second electrical connection part is electrically separated with the first electrical connection part, the first electrical conduction semiconductor layer, and the active layer.
