Abstract: In a display device including a flexible display panel, the risk of disconnection of a wiring due to bending is reduced. A display panel includes a display function layer including display elements and a wiring on one major surface of a base material having flexibility. The display panel includes, on the one major surface of the base material, an organic-film-covered wiring area where the surface of the wiring is covered with an organic planarization film that is an organic insulating film in direct contact with the wiring. The display panel includes, in the plane thereof, a display area where the display elements are arranged and a component mounting area that is a peripheral area located outside the display area. As the organic-film-covered wiring area, a curved area is provided in the peripheral area.
