A highly efficient organic EL device having good field-of-view characteristics is disclosed. An organic electroluminescent device (1) comprises a transparent electrode (12) and a counter electrode (14) arranged opposite to the transparent electrode (12), and one or more intermediate conductive layers (30, 32, 34) and one or more organic light-emitting layers (20, 22, 24, 26) arranged between the transparent electrode (12) and the counter electrode (14). When the refractive index of the intermediate conductive layer (30) is na and the refractive index of the organic light-emitting layer (20) is nb, the difference between na and nb is 0.2 or less. |
