发明名称 ORGANIC ELECTROLUMINESCENCE ELEMENT
摘要 The present invention addresses the problem of providing an organic EL element having little color variation. The organic EL element (1) of the present invention is characterized in that between an anode (4) and cathode (14) pair, a first luminescent layer (8) comprising at least one layer, and a second luminescent layer (10) comprising at least one layer are stacked from the anode (4) side, and the volume concentration of a luminescent dopant contained in the second luminescent layer (10) is higher than the volume concentration of a luminescent dopant contained in the first luminescent layer (8).
