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.

Claims (14)

1. A flexible panel comprising:

a substrate having flexibility;

a pixel area including a thin film transistor arranged on the substrate;

a peripheral area located outside the pixel area;

a first inorganic film on the substrate;

a second inorganic film on the first inorganic film; and

a wiring on the second inorganic film disposed in the peripheral area,

wherein a first step portion of the substrate is arranged along an edge of the first inorganic film in the peripheral area, and

the wiring is disposed from the pixel area to the peripheral area.

2. The flexible panel according to claim 1 , wherein a second step portion of the first inorganic film is arranged in the peripheral area.

3. The flexible panel according to claim 1 , wherein

the substrate includes a curved portion in the peripheral area, and

the curved portion includes the first step portion of the substrate.

4. The flexible panel according to claim 1 , wherein the substrate is polyimide.
