    摘要： Disclosed is an organic electroluminescent element having an element structure that can reduce damage to an organic layer during electrode formation and can facilitate the injection of charges from the electrode into the organic layer. The organic electroluminescent element includes an anode, a cathode, and an organic layer held between the anode and the cathode. The organic layer contains a luminescent material. The organic electroluminescent element further includes a transparent protective layer provided between the anode or the cathode and the organic layer. The transparent protective layer contains a bipolar charge transport organic compound and an electron-accepting compound. The transparent protective layer is formed in a period between after the formation of the organic layer and before the formation of the anode or the cathode on the organic layer.

    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： 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.
