    摘要： The present invention provides a method for manufacturing an electroluminescence element that has a light emitting layer containing a quantum dot and exhibits excellent life characteristics. In the method, patterning of the light emitting layer can be stably performed by a lift-off method. A photoresist layer is formed on a substrate having a first electrode layer. The photoresist layer is then exposed, developed, and patterned to ensure that a portion of the photoresist layer, which is located in a light emission area, is removed. A coating liquid containing a quantum dot having a silane coupling agent attached to the surface thereof is coated on the resultant substrate having the patterned photoresist layer and cured to form a light emitting layer. The remaining photoresist layer is then removed to lift off a portion of the light emitting layer, which is present on the photoresist layer.

    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.
