Abstract:
1. A method of producing an organic EL element comprising a substrate, pixel electrodes disposed on a predetermined position of the substrate, a partition pattern for separating adjacent pixel electrodes, at least one luminescent layer formed on the pixel electrodes, and a counter electrode formed on the luminescent layer, which comprises the steps of: forming the pixel electrodes in a predetermined pattern on a surface of the substrate; making a surface of the pixel electrodes and a donor sheet come closely into contact with each other, the donor sheet comprising a base, a light-to-heat conversion layer formed over the base, and a transfer layer containing an image component comprising 0.05% by weight of a fluororesin formed over the light-to-heat conversion layer; forming the partition pattern over the substrate by irradiating laser beam from a base side of the donor sheet corresponding to the partition pattern to melt the image component with heating and to pile up the molten image component over the substrate; and filling an opening portion surrounded by the formed partition pattern with a water-based organic material having a predetermined color using an ink-jet method to form the luminescent layer.
