1. A micro-light emitting diode (LED) display comprising:
a backplane substrate; and
a plurality of sub-pixels provided on the backplane substrate,
wherein at least one sub-pixel from among the plurality of sub-pixels comprises:
a first region and a second region;
a first micro-LED provided in the first region; and
two or more second micro-LEDs that are different from the first micro-LED and provided in the second region,
wherein the first region and the second region have a same size of area, and
wherein the first micro-LED and the two or more second micro-LEDs have a same light emission characteristic, and a size of the first micro-LED is greater than a size of each of the two or more second micro-LEDs.
