Title (EN) DISPLAY PANEL, DISPLAY DEVICE, DISPLAY MODULE, AND ELECTRONIC DEVICE
(FR) PANNEAU D'AFFICHAGE, DISPOSITIF D'AFFICHAGE, MODULE D'AFFICHAGE, ET DISPOSITIF ÉLECTRONIQUE
Abstract:
(EN) A display panel or a display device with high display quality is provided. The display panel includes a light-emitting element, an insulating layer, a protective layer, and a conductive layer. The light-emitting element includes a first electrode, a light-emitting layer, and a second electrode. The light-emitting element emits light to the protective layer side. The insulating layer includes a first opening overlapping with the first electrode. The insulating layer covers an end portion of the first electrode. The light-emitting layer overlaps with the first electrode through the first opening. The second electrode is positioned over the light-emitting layer. The protective layer is over and in contact with the second electrode. The protective layer functions as a protective layer of the light-emitting element. The protective layer includes a second opening overlapping with the insulating layer. The conductive layer is connected to the second electrode through the second opening. The conductive layer functions as an auxiliary wiring of the second electrode.
(FR) La présente invention concerne un panneau d'affichage ou un dispositif d'affichage à haute qualité d'affichage. Le panneau d'affichage comprend un élément électroluminescent, une couche isolante, une couche protectrice et une couche conductrice. L'élément électroluminescent comprend une première électrode, une couche électroluminescente et une seconde électrode, et émet de la lumière vers le côté couche protectrice. La couche isolante comprend une première ouverture chevauchant la première électrode et recouvre une partie d'extrémité de la première électrode. La couche électroluminescente chevauche la première électrode par l'intermédiaire de la première ouverture. La seconde électrode est positionnée sur la couche électroluminescente. La couche protectrice se trouve au-dessus de la seconde électrode et en contact avec cette dernière, sert de couche protectrice à l'élément électroluminescent, et comprend une seconde ouverture chevauchant la couche isolante. La couche conductrice est connectée à la seconde électrode par l'intermédiaire de la seconde ouverture et sert de câblage auxiliaire à la seconde électrode.
