1. A display device, comprising:
a resin substrate defining a display region, a frame region around the display region, a terminal unit at an end of the frame region, and a fold portion provided between the terminal unit and the display region and extending in a single direction;
a TFT layer provided on the resin substrate, and including a plurality of display wires formed in the display region, the display wires extending in parallel with one an other, and intersecting with a longitudinal direction of the fold portion;
a plurality of light-emitting elements provided on the TFT layer and included in the display region;
a plurality of terminals included in the terminal unit and arranged in the longitudinal direction of the fold portion;
at least one inorganic insulating film provided on the resin substrate, included in the TFT layer, and including a slit formed in the longitudinal direction of the fold portion;
a first resin layer provided to fill the slit;
a plurality of first routed wires provided above the first resin layer, extending in parallel with one an other and intersecting with the longitudinal direction of the fold portion, and each electrically connected to a corresponding one of the display wires toward the display region and to a corresponding one of the terminals toward the terminal unit; and
a first protective layer formed between, and in contact with, the first resin layer and the first routed wires, and provided to at least partially coincide with each of the first routed wires, wherein
the first protective layer includes a plurality of first protective layers provided to match a transverse end of each of the first routed wires.
