DONOR FILM FOR LOW MOLECULE FULL COLOR ORGANIC EL ELEMENT USING LASER TRANSFER METHOD AND MANUFACTURING METHOD OF LOW MOLECULE FULL COLOR ORGANIC EL ELEMENT USING THIS FILM

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a donor film for a low molecule full color organic EL element and the organic EL element.;SOLUTION: This donor film for the low molecule full color organic EL element is composed of a substrate film, a photothermal conversion layer on the substrate film, and a transcription layer consisting of low molecular substance on the photothermal conversion layer, and one part of the transcription layer irradiated by the laser secedes by changes of adhesive force to the photothermal conversion layer, and the other part not irradiated by a laser is fixed to the photothermal conversion layer by the adhesive force, and the adhesive force between the substrate to which the low molecular substance of the transcription layer is transcribed and the low molecular substance, and the adhesive force between the photothermal conversion layer and the low molecular substance are larger than the ones between the low moleculr substance in the region irradiated by the laser in the transcription layer and the low molecular substance in the region not irradiated by a laser, and the low molecular substances in the region irradiated by the laser and in the region not irradiated by the laser are mutually separated from each other, and the material transition has occurred from the photothermal conversion layer to the substrate.;COPYRIGHT: (C)2004,JPO&NCIPI
