Donor film for thermal transfer, method of manufacturing the same, and method of manufacturing organic light-emitting device using the donor film

A method of manufacturing a donor film for thermal transfer, the method comprising:

• preparing a base film;
• forming a light-to-heat conversion (LTHC) layer for converting light to heat, on the base film;
• forming an interlayer on the LTHC layer, the forming of the interlayer comprising forming a transfer region and forming a first protrusion to correspond to at least one edge of the LTHC layer, a rigidity of the first protrusion being higher than a rigidity of the transfer region;
• and
• forming a transfer layer comprising an organic material, on the interlayer.

A method of manufacturing an organic light-emitting device, the method comprising:

• forming a donor film for thermal transfer, the forming of the donor film comprising:

• forming an interlayer on the LTHC layer, the forming of the interlayer comprising forming a transfer region and forming a first protrusion to correspond to at least one edge of the LTHC layer, a rigidity of the first protrusion being higher than a rigidity of the transfer region;
• and
• forming a transfer layer comprising an organic material, on the interlayer;
• preparing a substrate comprising a first electrode;
• covering the substrate with the donor film;
• forming an organic light-emitting layer, the forming of the organic light-emitting layer comprising transferring the transfer layer of the donor film to the first electrode;
• and
• forming a second electrode on the organic light-emitting layer.
