<p>An organic electroluminescence element comprising, on a substrate, an anode, a cathode, and a light emitting unit between the anode and the cathode, characterized in that the organic electroluminescence element has a structure such that the light emitting unit has at least three light emitting layers, the at least three light emitting layers have at least two kinds of light emitting layers different in light emitting peak, and a light emitting layer having a light emitting peak at the shortest wavelength, out of the light emitting layers owned by the light emitting unit, is held between light emitting layers having light emitting peaks at larger wavelengths, whereby a high light emission efficiency is obtained.</p> |
