Abstract:
(EN) The present invention is provided with: a plurality of pixels which are arranged on one surface of a substrate in a display region and each of which has a light-emitting element; a partition wall layer including a first partition wall, a second partition wall, and a third partition wall; an encapsulation layer which is provided on a layer over the plurality of pixels and the partition wall layer and includes a first inorganic insulating layer, an organic insulating layer, and a second inorganic insulating layer; a protective layer provided on the encapsulation layer; and a plurality of connection terminals disposed outside the protective layer. The first partition wall surrounds each of the plurality of pixels, the second partition wall surrounds the display region, and the third partition wall surrounds the outside of the second partition wall. A groove part is provided between the third and second partition walls. The organic insulating layer is provided on the first inorganic insulating layer, the second inorganic insulating layer is provided on the organic insulating layer, the organic insulating layer has an end part disposed between the first partition wall and the second partition wall or on the second partition wall, and the first inorganic insulating layer, the second inorganic insulating layer, and the protective layer have end parts disposed further outside than the end part of the second partition wall.
(FR) La présente invention comporte : une pluralité de pixels qui sont agencés sur une surface d’un substrat dans une zone d’affichage et dont chacun a un élément électroluminescent ; une couche de parois de séparation incluant une première paroi de séparation, une deuxième paroi de séparation, et une troisième paroi de séparation ; une couche d’encapsulation qui est disposée sur une couche au-dessus de la pluralité de pixels et de la couche de parois de séparation et qui inclut une première couche isolante inorganique, une couche isolante organique, et une deuxième couche isolante inorganique ; une couche protectrice disposée sur la couche d’encapsulation ; et une pluralité de bornes de connexion disposées à l’extérieur de la couche protectrice. La première paroi de séparation entoure chaque pixel de la pluralité de pixels, la deuxième paroi de séparation entoure la zone d’affichage, et la troisième paroi de séparation entoure l’extérieur de la deuxième paroi de séparation. Une partie en rainure est disposée entre les troisième et deuxième couches de séparation. La couche isolante organique est disposée sur la première couche isolante inorganique, la deuxième couche isolante inorganique est disposée sur la couche isolante organique, la couche isolante organique a une partie d’extrémité disposée entre la première paroi de séparation et la deuxième paroi de séparation ou sur la deuxième paroi de séparation, et la première couche isolante inorganique, la deuxième couche isolante inorganique, et la couche protectrice ont des parties d’extrémité disposées plus à l’extérieur que la partie d’extrémité de la deuxième paroi de séparation.
(JA) 表示領域内で基板の一表面上に配列され、各々が発光素子を有する複数の画素と、第1隔壁、第2隔壁及び第3隔壁を含む隔壁層と、複数の画素及び隔壁層の上層に設けられ、第1無機絶縁層、有機絶縁層及び第2無機絶縁層を含む封止層と、封止層の上層に設けられた保護層と、保護層の外側に配置された複数の接続端子とを備え、第1隔壁は、複数の画素の各々を囲み、第2隔壁は、表示領域を囲み、第3隔壁は、第2隔壁の外側を囲み、第3隔壁と第2隔壁の間に溝部を有し、有機絶縁層は、第1無機絶縁層上に設けられ、第2無機絶縁層は、有機絶縁層上に設けられ、有機絶縁層は、端部が第1隔壁及び第2隔壁の間または第2隔壁上に配置され、第1無機絶縁層、第2無機絶縁層及び保護層は、端部が第2隔壁の端部より外側に配置されている。
