Abstract
One aspect of the present disclosure provides a method of manufacturing a display device, including: a process of aligning a first wafer on which a plurality of first LEDs, a plurality of alignment keys, and a reference member are disposed with a donor substrate; a process of transferring the plurality of first LEDs and the reference member on the first wafer to the donor substrate; and a process of aligning a second wafer on which a plurality of second LEDs is disposed with the donor substrate based on the reference member. Therefore, a relative position between the plurality of second LEDs of the second wafer and the plurality of first LEDs of the donor substrate may be precisely aligned based on the reference member that maintains a predetermined interval from the plurality of first LEDs.
