Abstract
The disclosure relates to a light emitting diode (LED) that is capable of emitting a plurality of lights having different wavelengths from one another, and independently controlling the intensity of the plurality of emitted lights and a manufacturing method of the LED, and a display device including the LED. Specifically, an LED according to the disclosure includes a first light emitting cell including an n-type semiconductor layer, a p-type semiconductor layer, and a first light emitting layer which respectively include at least one non-planar area, the first light emitting layer emitting a light of a first wavelength, a second light emitting cell including an n-type semiconductor layer, a p-type semiconductor layer, and a second light emitting layer which respectively consist of a planar area, the second light emitting layer emitting a light of a second wavelength different from the first wavelength of the light emitted from the first light emitting layer, a common electrode commonly connected with the first light emitting cell and the second light emitting cell, and a first pixel electrode and a second pixel electrode independently connected with each of the first light emitting cell and the second light emitting cell.
