1. An electronic device comprising:
an insulating base including a strip-shaped portion having elasticity and an island-shaped portion connected to the strip-shaped portion;
an organic insulating film disposed on the insulating base;
an inorganic insulating film disposed on the organic insulating film;
a wiring disposed between the strip-shaped portion and the organic insulating film;
an electrical element disposed on the inorganic insulating film and electrically connected to the wiring, in the island-shaped portion;
a barrier wall overlapping the island-shaped portion and the strip-shaped portion and surrounding the electrical element; and
a sealing film covering the electrical element, wherein
the barrier wall comprises:
a first layer which is in contact with the inorganic insulating film; and
a second layer formed of an inorganic insulating material which is the same as a material of the sealing film, and stacked on the first layer,
the second layer is in contact with the sealing film,
the first layer includes a first side surface facing the electrical element, a second side surface on a side opposite to the first side surface, and a first upper surface,
the second layer includes a bottom surface which is in contact with the first upper surface,
the bottom surface extends from the first side surface toward the electrical element and extends from the second side surface toward an outside, and
the sealing film is in contact with the first side surface, the second side surface, and the bottom surface.
