ORGANIC ELECTROLUMINESCENT ELEMENT |
| 摘要 |
Provided is an organic EL element having less color variation. The organic EL element (1) of the invention includes, between a pair of an anode (4) and a cathode (14), a first light emitting layer (8) composed of at least one layer and a second light emitting layer (10) composed of at least one layer, the layers being laminated from the anode (4) side, in which the volume concentration of the luminescent dopant included in the second light emitting layer (10) is higher than the volume concentration of the luminescent dopant included in the first light emitting layer (8). |
