Flexible panel
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.
1. A flexible panel comprising:
a substrate having flexibility;
a pixel area, in which thin film transistors are arranged, on the substrate;
a peripheral area outside the pixel area in plan view;
a first inorganic film on the substrate;
a second inorganic film on the first inorganic film;
a wiring on the second inorganic film disposed in the peripheral area; and
an organic insulating film on the wiring,
wherein the peripheral area comprises a first area which includes the first inorganic film and the second inorganic film, a second area which includes the first inorganic film, and a third area without the first inorganic film and the second inorganic film,
a first step is formed at a boundary between the first area and the second area,
a second step is formed at a boundary between the second area and the third area, and
the wiring is disposed across the first step and the second step.
2. The flexible panel according to claim 1 , wherein
the wiring is in contact with the second inorganic film in the first area, the first inorganic film in the second area, and the substrate in the third area.
3. The flexible panel according to claim 1 , wherein
the organic insulating film covers the wiring and is in contact with the wiring in the third area.
4. The flexible panel according to claim 1 , wherein
the substrate includes a curved portion in the peripheral area, and
the curved portion is in the third area.
5. The flexible panel according to claim 1 , wherein
the substrate is made of material including polyimide.
