Light emitting diode, manufacturing method of light emitting diode and display device including light emitting diode

A light emitting diode (LED) comprising:

• a substrate;
• a first light emitting cell including a first n-type semiconductor layer, a first p-type semiconductor layer, a first light emitting layer and a first pixel electrode which respectively include a plurality of non-planar areas formed according to a plurality of protrusions facing upward with respect to the substrate, the first light emitting layer emitting a light of a first wavelength corresponding to a red color;
• a second light emitting cell including a second n-type semiconductor layer, a second p-type semiconductor layer, a second light emitting layer and a second pixel electrode which respectively include 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;
• and
• a common electrode commonly connected with the first light emitting cell and the second light emitting cell,
• wherein the first pixel electrode and the second pixel electrode independently connected with each of the first light emitting cell and the second light emitting cell,
• wherein the first light emitting cell and the second light emitting cell are separated horizontally by a region including a passivation layer, and
• wherein a first light emitting area of the first light emitting cell is larger than a second light emitting area of the second light emitting cell.
