1. A display device including a display region, a frame region, a film layer, a TFT layer, a terminal, and a fold portion, the display region including a plurality of display elements, the frame region surrounding the display region, the TFT layer stacked on top of the film layer in a stated order, the TFT layer including at least one inorganic insulating film, the terminal and the fold portion in the frame region, the fold portion being formed between the terminal and the display region, the display device comprising:
an inorganic-insulating-film first slit provided to the at least one inorganic insulating film and a film-layer first slit provided to the film layer, the inorganic-insulating-film first slit and the film-layer first slit overlapping at least the fold portion and extending in a direction to intersect with an edge of the frame region;
a first resin film included in the TFT layer and provided to Fill the inorganic-insulating-film first slit;
a plurality of connection wires provided above the at least one inorganic insulating film and the first resin film to overlap, and to intersect with, the fold portion, the connection wires electrically connecting the terminal to a wire in the display region; and
either an inorganic-insulating-film second slit overlapping the fold portion and intersecting with the inorganic-insulating-film first slit, or a film-layer second slit overlapping the fold portion and intersecting with the film-layer first slit, and either the inorganic-insulating-film second slit, or the film-layer second slit provided between pluralities of the connection wires adjacent to each other.
