A display device comprises an organic EL substrate including an organic EL layer formed on a flexible substrate and a first main surface of the flexible substrate; a film covering a display region of the organic EL substrate; and a terminal region arranged at an end portion of the organic EL substrate, and arranged adjacent to and apart from an end portion of the film. The end portion of the film may have a taper region. A thickness of the taper region increases with distance from the terminal region in a cross-sectional view. A width of the taper region may be 0.5 times or more and 1.5 times or less of the film thickness in a plan view.
