Abstract
A donor film that is easily handled in a process without adding a separate member (such as a tray) when an organic thin film is formed on a substrate by using a thermal transfer method is disclosed. In addition, a method of manufacturing the donor film and a method of manufacturing an organic light-emitting device using the donor film are disclosed. The donor film includes: a base film; a light-to-heat conversion (LTHC) layer on the base film; an interlayer on the LTHC layer and that includes a transfer region and a first protrusion corresponding to at least one edge of the LTHC layer; and a transfer layer on the interlayer and including an organic light-emitting material. A rigidity of the first protrusion is higher than a rigidity of the transfer region.
