Abstract: A semiconductor light emitting device includes a light emitting structure, a first electrode unit, and a second electrode unit. The light emitting structure includes a first and second conductivity-type semiconductor layer, an active layer. The first electrode unit includes a first electrode pad and a first electrode finger extending from the first electrode pad, and having an annular shape with an open portion. The second electrode unit includes a second electrode pad and a second electrode finger extending from the second electrode pad, and has an annular shape with an open portion. One of the first and second electrode units substantially surrounds the other, and the center of the annular shape of at least one of the first and second electrode units is spaced apart from the center of the upper surface of the light emitting structure.
