Abstract
A light emitting device package includes a light emitting structure including a first light emitting cell, a second light emitting cell, and a third light emitting cell, each of the first to third light emitting cells including an active layer to emit light of a first wavelength in a first direction and being separated from each other in a second direction, orthogonal to the first direction, a first light adjusting portion including a first wavelength conversion layer in a first recess portion of the first light emitting cell, the first wavelength conversion layer to convert light of the first wavelength to light of a second wavelength, and a second light adjusting portion including a second wavelength conversion layer in a second recess portion of the second light emitting cell, the second wavelength conversion layer to convert light of the first wavelength to light of a third wavelength.
