PROBLEM TO BE SOLVED: To provide an organic EL panel in which deterioration of recombination amount of holes and electrons in a luminous layer is suppressed and a long life emitting for a long period of time with a prescribed luminance is realized. SOLUTION: The organic EL panel 1 has an organic EL element 8 made by interposing an organic layer 5 between a positive electrode (transparent electrode) 3 and a negative electrode (backplate) 5 on a translucent support substrate 2. The organic layer 5 comprises at least an electron transporting first luminous layer 5c located on the positive electrode 3 side, and a hole transporting second luminous layer 5d located on the negative electrode 5 side.
