A display device using semiconductor light emitting devices is disclosed. The display device includes a substrate, a plurality of first electrodes disposed on the substrate, a light emitting device array comprising a plurality of semiconductor light emitting devices electrically connected to the first electrodes, constituting individual pixels, and having different brightnesses increasing from one side of a current input direction of each of the first electrodes to the other side of the current input direction, and a plurality of second electrodes electrically connected to the semiconductor light emitting devices. Thus, brightness variation caused by power loss may be reduced in a display device of PM type using light emitting device array, thereby reducing load effect that is a problem of the device of PM type using light emitting device array.
