DISPLAY DEVICE

This display device has: a base substrate; a thin-film transistor layer provided on the base substrate, the thin-film transistor layer including an upper-layer insulation film and an organic resin layer; a plurality of light-emitting elements provided on the thin-film transistor layer, the plurality of light-emitting elements including a common functional layer that is formed in common on sub-pixels that constitute a display area; a sealing film provided so as to cover the plurality of light-emitting elements, the sealing film being such that a first inorganic insulation film and a second inorganic insulation film are laminated in the stated order; a non-display area provided in island form within the display area; an opening that is provided within the non-display area and passes through the base substrate; a first frame-shaped protrusion that is a non-display area between the opening and the display area, the first frame-shaped protrusion being provided on the upper-layer insulation film at the periphery along the opening; and an organic buffer layer provided to the side surface of the first frame-shaped protrusion, the organic buffer layer being sandwiched between the first inorganic insulation film and the second inorganic insulation film. The first frame-shaped protrusion has a portion in which the area of a horizontal cross-section parallel to the upper surface of the base substrate decreases from the upper surface toward the bottom surface. The common functional layer is also provided in the non-display area. A slit that surrounds the first frame-shaped protrusion is formed in the common functional layer provided to the non-display area. L'invention concerne un dispositif d'affichage comprenant : un substrat de base ; une couche de transistor en couches minces disposée sur le substrat de base, la couche de transistor en couches minces comprenant un film d'isolation de couche supérieure et une couche de résine organique ; une pluralité d'éléments électroluminescents disposés sur la couche de transistor en couches minces, la pluralité d'éléments électroluminescents comprenant une couche fonctionnelle commune qui est formée en commun sur des sous-pixels qui constituent une zone d'affichage ; un film d'étanchéité disposé de façon à recouvrir la pluralité d'éléments électroluminescents, le film d'étanchéité étant tel qu'un premier film d'isolation inorganique et un second film d'isolation inorganique sont stratifiés dans l'ordre indiqué ; une zone de non
