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.
