Claim 0:
1. A display device comprising:
a resin substrate;
a thin film transistor layer provided on the resin substrate and including a first inorganic insulating film;
a light-emitting element layer provided on the thin film transistor layer and including a plurality of light-emitting elements arranged corresponding to a plurality of subpixels constituting a display region; and
a sealing film provided on the light-emitting element layer to cover the light-emitting elements and including a second inorganic insulating film,
a frame region being provided around the display region,
a non-display region being provided in an island shape within the display region,
a first electrode, a functional layer, and a second electrode being sequentially layered in each of the light-emitting elements, and
the functional layer including a common functional layer provided in common to the plurality of subpixels,
wherein an oxide semiconductor layer is provided in an island shape in the non-display region,
a first opening is provided in the first inorganic insulating film to expose the oxide semiconductor layer in the non-display region,
the common functional layer is provided to extend from the display region to the non-display region, and
a second opening is provided to expose the oxide semiconductor layer in the common functional layer, a peripheral end of the second opening being surrounded by a peripheral end of the first opening in a plan view.
