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 is a display device that includes a display area having an appearance of a specific color in a non-driving state or displaying a specific screen by using PDLC to improve esthetic appearance as in a home appliance. The display device comprises a reflective dispersed layer arranged on a display panel, wherein the reflective dispersed layer includes a PDLC layer between a first substrate and a second substrate, and a transflective layer arranged between the PDLC layer and the second substrate to transmit light externally emitted from the display panel and reflect externally incident light.
