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: Provided is a transfer method of a light emitting diode. The transfer method of the light emitting diode includes bonding a wafer in which a plurality of light emitting diodes is formed and a donor; transferring the plurality of light emitting diodes to the donor and detaching the wafer and the donor, the detaching of the wafer and the donor includes loading the bonded wafer and donor on a stage and a support member, fixing one of outermost portions of the donor by a fixing member, fixing one surface of the wafer to a head, moving the stage and the fixing member to a Z-axis direction, and moving the wafer and the head to an X-axis direction. Accordingly, the wafer and the donor are detached by the linear separation method to reduce the defective transfer of the plurality of light emitting diodes.

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.
