Abstract
A semiconductor light emitting device includes a light emitting structure in the form of a rod, including a first conductivity-type semiconductor layer, an active layer and a second conductivity-type semiconductor layer, and having a first surface, a second surface opposing the first surface, and a side surface connecting the first and second surfaces; a regrowth semiconductor layer surrounding an entire side surface of the light emitting structure and having a first thickness in a first position along a perimeter of the side surface and a second thickness, different from the first thickness, in a second position along a perimeter of the side surface; a first electrode on the first surface of the light emitting structure and connected to the first conductivity-type semiconductor layer; and a second electrode on the second surface of the light emitting structure and connected to the second conductivity-type semiconductor layer.
