Abstract:
A method of producing an organic LED display panel, the method comprising:preparing a donor film by forming a transfer film on a base film comprising at least a foundation film and a light-to-heat conversion layer, combining the donor film with a substrate and irradiating the donor film with one of a light beam and a heat radiation beam to pattern-transfer the transfer film from the donor film onto the substrate, wherein surfaces of the base film and the substrate which are to be brought into contact with the transfer film are hydrophilic or hydrophobic, and have water contact angles &thgr;1 and &thgr;2, respectively, which satisfy the following expression (I): &thgr;1âˆ’&thgr;2<50 degrees subjecting at least one of the surface of the base film and the surface of the substrate to one of a hydrophilation treatment and a hydrophobation treatment so that the expression (I) is satisfied.
