Classification: CPC H  G | IPC G  H

Claim 14:
15. A method for manufacturing a display device, the display device including:
a display region including a plurality of display elements;
a frame region surrounding the display region;
a film layer and a TFT layer stacked on top of the film layer in a stated order, the TFT layer including at least one inorganic insulating film; and
a terminal and a fold portion in the frame region, the fold portion formed between the terminal and the display region, the method comprising:
forming the film layer; and
forming the TFT layer,
the forming of the TFT layer including forming an inorganic-insulating-film first slit in the fold portion, and the forming of the film layer including a film-layer first slit in the fold portion, the inorganic-insulating-film first slit provided to the at least one inorganic insulating film, the film-layer first slit provided to the film layer, and the inorganic-insulating-film first slit and the film-layer first slit extending in a direction to intersect with an edge of the frame region,
the forming of the TFT layer further including:
forming a first resin film provided to fill the inorganic-insulating-film first slit; and
forming a plurality of connection wires provided above the at least one inorganic insulating film and the first resin film to overlap and to intersect the fold portion, the connection wires electrically connecting the terminal to a wire in the display region, and

the forming of the TFT layer including forming an inorganic-insulating-film second slit intersecting with the inorganic-insulating-film first slit in the fold portion, and the forming of the film layer including forming a film-layer second slit intersecting with the film-layer first slit in the fold portion, and either the inorganic-insulating-film second slit or the film-layer second slit provided between adjacent groups of the pluralities of the connection wires.
