Display device

A display device comprising:

• a resin substrate defining a display region display an image, a frame region in a periphery of the display region, a terminal portion at an end portion of the frame region, and a bending portion extending in one direction between the terminal portion and the display region;
• a TFT layer provided on the resin substrate and including a first metal film, a first inorganic insulating film, a second metal film, a first flattening film, a third metal film, and a second flattening film sequentially layered;
• and
• a light-emitting element provided on the TFT layer and including a plurality of pixel electrodes disposed on the second flattening film and an edge cover to cover a peripheral end portion of each of the plurality of pixel electrodes,
• wherein the first inorganic insulating film is provided with a slit in the bending portion, and the slit opens upward and extends in an extending direction of the bending portion,
• the display region side and the terminal portion side of the slit are provided with a plurality of first lead-out wiring lines and a plurality of second lead-out wiring lines formed of the first metal film, respectively, and the plurality of first lead-out wiring lines and the plurality of second lead-out wiring lines extend in parallel to each other in a direction intersecting the extending direction of the bending portion,
• the display region is provided with a plurality of first display wiring lines formed of the second metal film, the first flattening film covering each of the plurality of first display wiring lines, a plurality of second display wiring lines formed of the third metal film on the first flattening film, and the second flattening film covering each of the plurality of second display wiring lines,
• the bending portion is provided with a first resin film formed of the same material and in the same layer as those of the first flattening film, and the first resin film fills the slit,
• an upper face of the first resin film is provided with a plurality of first connection wiring lines formed of the third metal film, and the plurality of first connection wiring lines extend in parallel to each other in a direction intersecting the extending direction of the bending portion, and
• the plurality of first connection wiring lines are electrically connected to the plurality of first lead-out wiring lines, respectively in the display region side of the slit, and electrically connected to the plurality of second lead-out wiring lines, respectively in the terminal portion side of the slit, wherein a base of the slit is provided with a plurality of lower layer connection wiring lines formed of the second metal film, and the plurality of lower layer connection wiring lines extend in parallel to each other in a direction intersecting the extending direction of the bending portion, and the plurality of first connection wiring lines pass through the plurality of lower layer connection wiring lines, respectively via a contact hole formed in the first resin film.
