Abstract
A donor substrate, a method of laser induced thermal imaging, and a method of manufacturing an organic light emitting display device are disclosed. In the method of laser induced thermal imaging, a donor substrate is provided to include a base substrate, a light to heat conversion layer, a transfer layer and a functional layer. The functional layer includes a material radiating an infrared light. The donor substrate is laminated to an acceptor substrate. A laser beam is radiated into the donor substrate, thereby forming an organic layer pattern on the acceptor substrate from the transfer layer. A position of the organic layer pattern is observed using an infrared microscope. A laser beam position is adjusted and the donor substrate is separated from the acceptor substrate.
