| 摘要 |
An organic light-emitting diode comprising a substrate (1), an organic light-emitting layer (3) arranged between a first electrode (2) and a transparent and semi-reflecting second electrode with a multilayer structure subdivided into: a first silver-based metallic layer (4) in contact with the organic light-emitting layer (3), a second aluminum-based metallic layer (5), and a third dielectric layer (6), characterized in that the second metallic layer (5) is inserted between the first metallic layer (4) and the third dielectric layer (6) of the transparent second electrode, that the organic light-emitting layer (3) comprises a doped sub-layer in contact with the first metallic layer (4) of the transparent second electrode, and that the thickness of said third dielectric layer (6) is adjusted to limit the absorption by said first (4) and second (5) metallic layers of the light emitted by the diode.
