DISPLAY DEVICE
A display device includes a substrate, a plurality of pixels above the substrate, each of the pixels including a light emitting element, a display region including the plurality of pixels, a thin film transistor which each of the plurality of pixels includes, a protective film including a first inorganic insulating material and located between the thin film transistor and the light emitting element, a sealing film including a second inorganic insulating material and covering the light emitting element, and at least one through hole located in the display region and passing through the substrate, the protective film, and the sealing film, wherein the second inorganic insulating material is in direct contact with the protective film in a first region located between the through hole and the pixels.
1 . A display device comprising:
a substrate;
a light emitting element arranged on the substrate;
a thin film transistor arranged on the substrate and connected to the light emitting element;
an interlayer insulating film covering a gate electrode of the thin film transistor;
a planarization film arranged above the thin film transistor and under the light emitting element;
a sealing film arranged on an upper side of the light emitting element; and
a display region including a plurality of the light emitting element,
wherein
the substrate includes at least one or a plurality of through holes,
a first region is arranged along an outer periphery of the through hole in the display region,
the interlayer insulating film has an inclined side surface facing through hole,
the sealing film is directly contact with the interlayer insulating film at the first region and covers the inclined side surface of the interlayer insulating film.
2 . The display device according to claim 1 , wherein
the planarization film has an opening side surface along the outer periphery of the through hole.
