1. A display device comprising:
a substrate including a plurality of first sub-pixels, a plurality of second sub-pixels, a plurality of third sub-pixels;
a plurality of first semiconductor light emitting devices disposed in the plurality of first sub-pixels, and configured to generate first color light of a first main wave;
a plurality of second semiconductor light emitting devices disposed in the plurality of second sub-pixels, and configured to generate second color light of a second main wave; and
a plurality of third semiconductor light emitting devices disposed in the plurality of third sub-pixels, and configured to generate third color light of a third main wave,
wherein at least some of the plurality of first semiconductor light emitting devices have different light emitting regions to compensate for a wave deviation of the first main wave, and
wherein each of the plurality of first semiconductor light emitting devices further comprises:
a first-first conductivity type semiconductor layer;
an active layer on the first-first conductivity type semiconductor layer;
a first-second conductivity type semiconductor layer disposed on the active layer and having a first region and a second region surrounding the first region; and
a current blocking layer on the second region of the first-second conductivity type semiconductor layer.
