Abstract: A display device and a method of manufacturing the same are disclosed. The display device comprises a thin film transistor on a substrate, a protective film on the thin film transistor, and an alignment film on the protective film. The protective film includes one or more protective films, and a protective film adjacent to the alignment film among the one or more protective films has a silicon content higher than a nitrogen content. Thus, it is possible to provide a display device capable of reducing image sticking or flicker.

Abstract: The organic light-emitting display device comprises a substrate having a folding axis extending in a first direction, the substrate including a folding area configured to curve around the folding axis in a second direction intersecting the first direction; a first anode on the substrate; a bank layer on the substrate; and a plurality of first spacers provided on the bank layer in the folding area and disposed in the second direction. The plurality of first spacers comprises a first-first spacer extending in a direction deviating from the first direction and the second direction when viewed in a plan view; and a first-second spacer spaced apart from the first-first spacer in the second direction and extending in a direction parallel to the direction in which the first-first spacer extends. The first-first spacer and the first-second spacer at least partially overlap each other when viewed in the plan view.
