An organic EL device includes a transparent substrate (31), an anode (32),
a hole injection layer (33), a hole transport layer (34), an luminescent
layer (35), an electron transport multilayered body (36), a cathode-side
electron transport layer (37), and a cathode (38) formed on the substrate
(31) in that order. The electron transport multilayered body (36)
includes alternate layered two kinds of electron transport layers (36A,
36B) having electron affinities that are different from each other. Increasing
the amount of electron current injected from the cathode (38) for balancing
with the amount of hole current, and enhancing luminous efficiency.
