Abstract: An organic electroluminescence (EL) element that has an anode; a cathode; an organic light-emitting layer between the anode and the cathode that emits light according to recombination of holes injected from the anode and electrons injected from the cathode; and an electron transport layer between the cathode and the organic light-emitting layer that transports electrons from the cathode to the organic light-emitting layer. The electron transport layer includes an n-type dopant that includes an electron-donating substance, the electron transport layer being doped with the n-type dopant at a doping concentration that is higher than a doping concentration at which light emittance efficiency of the organic light-emitting layer is greatest.

Abstract: A method for manufacturing a joined body composed of a first substrate and a second substrate joined together by sealing resin material attached to a predetermined area of the first substrate includes: attaching a sheet material to the first substrate so as to cover the predetermined area, the sheet material including a sheet base material and the resin material provided on one main surface of the sheet base material; forming, after the attaching, in the sheet material, a slit by reducing a thickness of the resin material along an outline of the predetermined area; and separating, after the forming, part of the resin material inside the slit from the sheet base material to keep the part of the resin material inside the slit on the predetermined area of the first substrate and not to keep the rest of the resin material outside the slit on the first substrate.

Abstract: A display panel comprises a first substrate, a second substrate arranged opposite the first substrate, electroluminescence elements disposed between the first substrate and the second substrate, and a sealing member provided between the first substrate and the second substrate, sealing the electroluminescence elements. The sealing member includes a rectangular frame formed along a perimeter of the electroluminescence elements and a reinforced portion protruding outward from a corner portion of the rectangular frame, the reinforced portion includes a first side face cut so as to be flush with at least one corner side face of the first substrate, and a second side face cut so as to be flush with a corresponding corner side face of the second substrate.
