摘要： A process for producing an electroluminescent device comprises the steps of preparing a substrate 1, forming a first electrode layer 2 on the substrate 1, and forming a luminescent layer 3 on the first electrode layer 2 by applying a luminescent-layer-forming coating liquid containing quantum dots 22, each quantum dot 22 being surrounded by organic ligands 21. After the luminescent-layer-forming step, the step of removing the organic ligands 21 from the quantum dots 22 by subjecting the luminescent layer 3 to UV-ozone cleaning is performed. After the organic-ligand-removing step, the step of forming a second electrode layer 4 on the luminescent layer 3 in which the organic ligands 21 have been removed from the quantum dots 22 is performed.

摘要： A primary object of this invention is to provide a manufacturing method for an EL element, which can facilitate patterning for a luminescent layer containing quantum dots. This method includes: a wettability-changing-layer-forming step for forming a wettability changing layer containing a photocatalyst, on a substrate having a first electrode layer formed thereon, wherein wettability of the wettability-changing layer is changed by an effect of the photocatalyst associated with irradiation with energy; and a wettability-changing-pattern forming step for forming a wettability changing pattern composed of lyophilic regions and liquid-repellent regions, on a surface of the wettability changing layer, by irradiating the wettability changing layer with energy in a patterning manner. Additionally, in this method, a luminescent layer is formed onto each lyophilic region, by coating a luminescent-layer-forming coating liquid containing the quantum dots, around each of which ligands are attached. In this way, the EL element can be obtained.
