    Abstract: A method of manufacturing a display device is disclosed. The method comprises aligning a first wafer with a donor substrate, the first wafer including a first light emitting diodes (LEDs), first alignment keys, and second alignment keys. The method comprises transferring the first LEDs and a portion of the second alignment keys included in the first wafer onto the donor substrate. The method comprises aligning a second wafer with the donor substrate, the second wafer including second LEDs, first alignment keys, second alignment keys, and third alignment keys of the second wafer. The second wafer is aligned with the donor substrate by aligning the portion of the second alignment keys of the first wafer that are disposed on the donor substrate with the third alignment keys of the second wafer.

    Abstract: A light emitting diode transfer method includes bonding a rigid substrate on which a plurality of light emitting diodes are formed and a flexible substrate, transferring the plurality of light emitting diodes to the flexible substrate, and detaching the rigid substrate and the flexible substrate. The detaching of the rigid substrate and the flexible substrate includes separating the rigid substrate and the flexible substrate in a state in which one surface of the rigid substrate is fixed and a portion among outermost portions of the flexible substrate is fixed by a fixing member. Accordingly, it is possible to reduce transfer defects of the plurality of light emitting diodes by detaching the flexible substrate and the rigid substrate in a line-by-line separation method.

    Abstract: 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.
