Display device

A display device including:

• a base substrate;
• a thin-film transistor layer provided on the base substrate, including at least one first inorganic insulating film, and having a surface on which a planarization film is stacked;
• a light-emitting element layer in which a plurality of light-emitting elements are arranged, the light-emitting clement layer being provided on the thin-film transistor layer;
• and
• a sealing film including at least one second inorganic insulating film, and provided on the light-emitting element,
• each of the light-emitting elements including:
• a first electrode;
• a functional layer;
• and a second electrode stacked on top of an other in a stated order,
• the display device including:
• a display region defined to display an image;
• a frame region defined around the display region;
• and a non-display region defined inside the display region and shaped into an island, and
• the non-display region including a through hole penetrating the non-display region along a thickness of the base substrate, the display device comprising
• a separation wall shaped into a frame and provided to the non-display region along an edge of the through hole,
• the separation wall including:
• a first resin layer formed of the same material, and in the same layer, as the planarization film is;
• and a first metal layer formed of the same material, and in the same layer, as the first electrode is, and provided on the first resin layer, and
• the first metal layer including a first protrusion shaped into a canopy, and protruding from the first resin layer toward the display region.
