Abstract:
A device transfer method and a display apparatus are provided. A device transfer method and a display apparatus are provided by or in which, in transferring devices arranged on a substrate onto another substrate, it is possible to easily strip the substrate after the transfer of the devices, to lower the possibility of damaging of the substrate, and to additionally transfer devices onto the same substrate after the transfer of the devices. A plurality of devices arranged on a temporary holding substrate are embedded into and held in a pressure sensitive adhesive layer formed on a transfer substrate, and the devices are stripped from the temporary holding substrate. Other devices are further additionally embedded into the pressure sensitive adhesive layer before hardening the pressure sensitive adhesive layer, whereby the devices can be arranged on a transfer substrate having a large area. Besides, where the devices additionally embedded into the pressure sensitive adhesive layer are different in characteristics from the devices embedded in the pressure sensitive adhesive layer in advance, it is possible to easily obtain a display apparatus for multicolor display, a display apparatus having a driving circuit, and the like.
