Display device

A display device comprising:

• a base substrate;
• a thin film transistor layer provided on the base substrate and including an upper layer insulating film and an organic resin layer;
• a plurality of light-emitting elements provided on the thin film transistor layer and each including a common function layer formed continuously across each subpixel constituting a display region;
• a sealing film covering the plurality of light-emitting elements and including a first inorganic insulating film and a second inorganic insulating film layered in that order;
• a non-display region provided in an island shape in the display region;
• an opening provided in the non-display region and passing through the base substrate;
• a first frame-shaped protruding portion serving as the non-display region between the opening and the display region and provided on the upper layer insulating film in a circumferential shape along the opening;
• and
• an organic buffer layer provided on a side surface of the first frame-shaped protruding portion and interposed between the first inorganic insulating film and the second inorganic insulating film,
• wherein the first frame-shaped protruding portion includes a portion where a distance of both side surfaces gradually narrows from an upper face to a bottom face,
• the common function layer is also provided in the non-display region, and
• a slit surrounding the first frame-shaped protruding portion is formed in the common function layer provided in the non-display region.
