Abstract
A transfer device in which a material which transmits a laser beam LB is employed as an upper mold, and a photothermal conversion layer is formed thereon. A transfer film, at which a transfer material layer is formed, and a workpiece are superposed and pressured between the upper mold and a lower mold. During this pressuring, the laser beam is irradiated in accordance with a pattern of an organic electroluminescent light-emitting layer that is to be formed on the workpiece. Thus, the photothermal conversion layer is heated and the transfer material layer is softened. As a result, the transfer material layer is cleaved and detached from a temporary support, and a component in the transfer material layer that is to form the organic electroluminescent light-emitting layer is transferred to the workpiece. Accordingly, efficient transfer processing is enabled when a transfer material is transferred to a transfer object by a thermal imaging process.
