1. A flexible display device, comprising:
a resin layer formed on a surface of one side of a flexible substrate; and
an inorganic film formed above the resin layer,
wherein the resin layer includes:
a central region;
an end region formed surrounding the central region and having a film thickness less than a film thickness of the central region; and
a central end region formed surrounding the central region and being surrounded by the end region, the central end region having a film thickness greater than the film thickness of the end region, and
the inorganic film includes:
four missing parts where a portion of the inorganic film is missing in the central end region, the four missing parts being formed individually along each of four different sides in the central end region.
