Abstract
Provided are a light emitting device, a light emitting device package, and a lighting system. The light emitting device includes a substrate, a light emitting structure on the substrate, the light emitting structure comprising a first conductive type semiconductor layer, a second conductive type semiconductor layer on the first conductive type semiconductor layer, and an active layer between the first and second conductive type semiconductor layers; a first electrode on the light emitting structure; and a patterned phosphor layer on the light emitting structure, wherein the patterned phosphor layer converts light generated from the light emitting structure into light having a wavelength longer than that of the light generated from the light emitting structure, and wherein the pattern of the phosphor layer exposes the first electrode.
