摘要： 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.
