Disclosed are a display device and a method of manufacturing a display device. The method of a display device according to an exemplary embodiment of the present disclosure includes: a first transferring step of transferring a plurality of LEDs disposed on a wafer onto a plurality of donors; and a second transferring step of transferring the plurality of LEDs transferred onto the plurality of donors onto a display panel, in which in the second transferring step, an area where one of the plurality of donors overlaps the display panel partially overlaps an area where the other one of the plurality of donors overlaps the display panel. Therefore, the plurality of LEDs having different wavelengths is uniformly transferred to reduce a boundary caused by the difference in wavelengths and improve color uniformity.
