Display device
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 display device comprising:
a first organic insulating film;
a curved area where the first organic insulating film is curved;
a non-curved area that is adjacent to the curved area;
a first inorganic film on the first organic insulating film in the non-curved area; and
a metal film which includes a first portion on the first organic insulating film in the curved area, a second portion on the first inorganic film and a third portion extending between the first portion and the second portion, wherein
the third portion is located in the non-curved area and covers an edge of the first inorganic film.
2. The display device according to claim 1 , wherein
the metal film is a wiring.
3. The display device according to claim 1 , wherein
the first organic insulating film has a display area and a peripheral area outside the display area, and
the non-curved area is in the peripheral area.
4. The display device according to claim 1 , further comprising:
a second organic insulating film on the metal film, wherein
a bottom surface of the metal film is in contact with the first organic insulating film, and
an upper surface of the metal film is in contact with the second organic insulating film.
5. The display device according to claim 4 , wherein
the second organic insulating film is in contact with a side surface of the metal film.
6. The display device according to claim 1 , further comprising:
a first insulating film on the first inorganic film, wherein
the metal film further includes a fourth portion on the first insulating film and a fifth portion extending between the second portion and the fourth portion, and
the fifth portion covers an edge of the first insulating film.
7. The display device according to claim 3 , further comprising:
a second inorganic film on the metal film, wherein
an edge of the second inorganic film is closer to the display area than the edge of the first inorganic film.
8. The display device according to claim 7 , wherein
the second inorganic film is in contact with the metal film.
9. A display device comprising:
a first organic insulating film;
a first inorganic film on the first organic insulating film; and
a wiring film which includes a first portion on the first organic insulating film, a second portion on the first inorganic film and a third portion extending between the first portion and the second portion, wherein
the third portion covers an edge of the first inorganic film.
10. The display device according to claim 9 , further comprising:
a curved area where the first organic insulting film is curved; and
a non-curved area that is adjacent to the curved area.
11. The display device according to claim 10 , wherein the third portion is located in the non-curved area.
12. The display device according to claim 10 , wherein
the first organic insulating film has a display area and a peripheral area outside the display area, and
the non-curved area is in the peripheral area.
13. The display device according to claim 9 , further comprising:
a second organic insulating film on the wiring film, wherein
a bottom surface of the wiring film is in contact with the first organic insulating film, and
an upper surface of the wiring film is in contact with the second organic insulating film.
14. The display device according to claim 13 , wherein the second organic insulating film is in contact with a side surface of the wiring film.
15. The display device according to claim 9 , further comprising:
a first insulating film on the first inorganic film, wherein
the wiring film further includes a fourth portion on the first insulating film and a fifth portion extending between the second portion and the fourth portion, and
the fifth portion covers an edge of the first insulating film.
16. The display device according to claim 15 , further comprising:
a curved area where the first organic insulating film is curved; and
a non-curved area that is adjacent to the curved area, wherein
the fifth portion is located in the non-curved area.
17. The display device according to claim 16 , wherein
the first organic insulating film has a display area and a peripheral area outside the display area, and
the fifth portion is closer to the display area than the third portion.
18. The display device according to claim 17 , further comprising:
a second inorganic film in contact with the wiring film.
