1. A flexible display device comprising:
a base layer in which a first resin layer, an inorganic film, and a second resin layer are layered in this order; and
a display element disposed on the base layer, wherein
in the base layer,
the inorganic film is provided such that the first resin layer and the second resin layer are layered to be in contact with each other in at least a portion of an outer edge portion of the base layer, wherein
a thickness of the base layer in a layer direction at a position where the second resin layer and the first resin layer are layered to be in contact with each other is smaller than that of the base layer in the layer direction at a position where the first resin layer, the inorganic film, and the second resin layer are layered in this order, wherein
the first resin layer, the inorganic film, the second resin layer, and the display element are provided in this order.
