    Abstract: PROBLEM TO BE SOLVED: To provide a light-emitting element improved in luminous efficiency, reduced in angle dependence of emission spectrum, and capable of realizing high quality emission showing an emission of desired color tone regardless of angle, and capable of adjusting the color tone.
    SOLUTION: The light-emitting element is formed by laminating a first light-emitting part formed by providing a first electrode, a luminous layer, and a second electrode in this order on a substrate and a second light-emitting part formed by providing a third electrode, a luminous layer, and a fourth electrode in this order on a substrate. A filling material having nearly equal refractive index to that of the substrates or electrodes is filled between the electrodes or substrates in contact of the first and the second light-emitting parts.

    Abstract: PROBLEM TO BE SOLVED: To provide an organic electroluminescent element of which the lifetime can be extended by improving a hole transport layer.
    SOLUTION: The organic electroluminescent element has an organic luminous layer 3 and an electron transport layer 4 formed by containing an electroluminescent dopant in a host material between two opposing electrodes 1, 2. A mixed layer 6 is provided at a part at least in contact with the organic luminous layer 3 in the hole transport layer 4, where the mixed layer 6 is made by mixing a main constituent for composing the hole transport layer 4, the host material of the organic luminous layer 3, and a material that has electron affinity that is not less than the electron affinity of a main constituent for composing the hole transport layer 4 and differs from the host material of the organic electroluminescent layer 3.

    Abstract: PROBLEM TO BE SOLVED: To provide a sealing member for an organic electroluminescent element in which injection of electric power with a low loss is possible without making a light emitting area smaller and in which connection to an external circuit is easily carried out with no need of working such as a through hole.
    SOLUTION: This is the sealing member A to seal an organic light emitting layer 3 of the organic electroluminescent element 4 formed by installing the organic light emitting layer 3 between two electrodes 1, 2. The sealing member A is provided with an auxiliary electrode 5, a conductive part 6 which is connected to the auxiliary electrode 5 and connectable and opposed to the electrodes 1, 2 of the organic electroluminescent element 4, and the external electrode 7 connected to the auxiliary electrode 5 and exposed on the outer face of the sealing member A. There is no need of making the light emitting area smaller as in the case the auxiliary electrode is installed at the electrodes 1, 2 formed at a transparent electrode of the organic electroluminescent element 4, and furthermore the external electrode 7 connected to the auxiliary electrode 5 is installed while exposed on the outer face of the sealing member A, thereby there is no need of working such as the through hole.
