Display device

A display device comprising:

• a resin substrate;
• a thin film transistor layer provided on the resin substrate and including an inorganic insulating film, wherein the thin film transistor layer includes, as the inorganic insulating film, a base coat film, a gate insulating film, and an interlayer insulating film that are sequentially layered on the resin substrate in this stated order;
• and
• a light-emitting element layer provided on the thin film transistor layer and arrayed with a plurality of light-emitting elements corresponding to a plurality of subpixels that forms a display region,
• wherein:
• a frame region is provided surrounding the display region,
• a terminal portion is provided at an end portion of the frame region,
• a bending portion is provided between the display region and the terminal portion, the bending portion extending in an extending direction,
• a slit is provided at the bending portion in the inorganic insulating film, the slit extending in the extending direction of the bending portion and exposing a surface of the resin substrate, wherein the slit includes a first slit provided in the gate insulating film and the interlayer insulating film as a first portion of the slit, the first slit exposing a surface of the base coat film, and a second slit provided in the base coat film as a second portion of the slit, the second slit exposing the surface of the resin substrate,
• a resin filling film is provided at the bending portion, the resin filling film filling the slit,
• a plurality of lead wiring lines is provided on the resin filling film, the plurality of lead wiring lines extending parallel with each other in a direction intersecting the extending direction of the bending portion,
• protrusions and recesses are alternately disposed in the extending direction of the bending portion on the surface of the resin filling film, each of the protrusions and recesses extending in a direction intersecting the extending direction of the bending portion, and
• at least one of the plurality of lead wiring lines is provided on a protrusion of the protrusions.
