PROBLEM TO BE SOLVED: To provide an organic light emitting element capable of materializing high quality luminescence showing luminescence with a desired color tone without relying on angles since angle dependency of emission spectrum is not much, and also capable of adjusting the color tone. SOLUTION: This organic light emitting element is formed by laminating a first light emitting part 4 formed by providing a luminescent layer 3 between a pair of electrodes 1, 2 and a second light emitting part 8 formed by providing a luminescent layer 7 between a pair of electrodes 5, 6. Among those four electrodes, one of the electrodes positioned on the outside is an electrode having light reflectivity, and all others electrodes are light-transmissive, and a light transmissive insulating layer 9 having such a thickness that light emitted in the luminescent layer 2 of the light emitting part 4 on the side having no light reflective electrode causes no interference and making light emitted in the luminescent layer 3 scatter is provided between the first light emitting part 4 and the second light emitting part 8.
