1. A display device comprising:
a resin substrate layer;
a thin film transistor layer provided on the resin substrate layer and including a lower inorganic insulating film, a lower wiring line layer, and an organic insulating film layered in order; and
a light-emitting element layer provided on the thin film transistor layer, and including a plurality of first electrodes, a plurality of light-emitting function layers, and a common second electrode layered in order corresponding to a plurality of subpixels constituting a display region,
wherein a non-display region with an island shape is provided inside the display region,
a through-hole passing through the resin substrate layer in the non-display region in a thickness direction is provided,
an electronic component is installed in the through-hole,
in the non-display region, a plurality of inner protruding portions each are provided to surround the through-hole,
each of the plurality of inner protruding portions includes a lower resin layer constituted by the resin substrate layer and a lower inorganic insulating layer provided on the lower resin layer and formed in the same layer with the same material as the lower inorganic insulating film,
the lower resin layer of each of the plurality of the inner protruding portions is separated by a plurality of inner slits each formed on a surface of the resin substrate layer on a side of the lower inorganic insulating film,
the lower inorganic insulating layer is provided to protrude from the lower resin layer in an eaves shape to at least one of a side of the through-hole and a side of the display region,
in the display region, a plurality of display wiring lines are provided to extend in parallel to each other as the lower wiring line layer,
some of the plurality of display wiring lines are separated by the through-hole,
at a bottom portion of each of the plurality of inner slits, a first non-display conductive layer is formed in the same layer with the same material as the second electrode, and
the first non-display conductive layer closest to the display region is provided to overlap each of the some of the plurality of display wiring lines separated by the through-hole at one end portion on a side of the through-hole and another end portion on a side of the through-hole.
