Abstract
Disclosed are a light emitting device and a method for manufacturing a light emitting device. The light emitting device according to the present application may be formed by an epitaxial growth process. In addition, the light emitting device according to the present application includes a first semiconductor layer, a light emitting layer and a second semiconductor layer. Light emitting wavelengths of the first region, the second region and the third region are different by setting composition of the light emitting layer of the top walls of the plurality of protrusions, the side walls of the plurality of protrusions and the recessed region between the plurality of protrusions to be different, therefore, the light-emitting device may emit light of different wavelengths without using phosphors or quantum dots for wavelength conversion, thereby prolonging the lifespan of the light-emitting device and improving the reliability of the light-emitting device.
