| 摘要 |
The invention relates to a electronic display device having an electroluminescent screen and to its manufacturing method. This device (1) comprises a substrate (2) coated with a matrix of pixels, each pixel formed by an organic emitting structure (5) intermediate between two electrodes, one (3) near and the other (4) far, relative to the substrate respectively, an electrically insulating resin (7) covering the substrate between the respective near electrodes of the pixels and furthermore extending onto a peripheral edge (3a) of each near electrode. According to the invention, each pixel incorporates at least one auxiliary electrode (8) which is transparent or semitransparent, which is based on a metallic material having a work function identical or substantially identical to that of the near electrode, and which extends inclinedly on the surface of the resin and facing said edge, from the near electrode towards the far electrode, so as to maximize the emission area of each pixel and to vary the thickness of the optical cavity formed between the near electrode of each pixel and the far electrode. This auxiliary electrode is implanted on the resin by dry etching of the material of the near electrode from which it is derived by ricochet.
