a bending portion is provided in the base member of the non-transmissive display section or the base member of the transmissive display section, and

the connecting section and the bending portion do not overlap each other,

wherein the base member of the non-transmissive display section includes a non-transmissive resin layer in which a plurality of resin films including a first polyimide resin film are stacked,

the base member of the transmissive display section includes a transmissive resin layer in which a plurality of resin films including a second polyimide resin film are stacked, and

the connecting section includes a convex-concave locking section in which at least one resin film in one of the non-transmissive resin layer and the transmissive resin layer is locked onto at least one resin film in another one of the non-transmissive resin layer and the transmissive resin layer,

wherein the convex-concave locking section anchors the at least one resin film in one of the non-transmissive resin layer and the transmissive resin layer to the at least one resin film in another one of the non-transmissive resin layer and the transmissive resin layer.

2. The display device according to claim 1 , wherein

the first polyimide resin film has a different thickness in the convex-concave locking section than in locations other than the convex-concave locking section, and

the second polyimide resin film has a different thickness in the convex-concave locking section than in locations other than the convex-concave locking section.

3. The display device according to claim 1 , wherein

the first polyimide resin film in the non-transmissive resin layer includes two first polyimide resin films, and

the second polyimide resin film in the transmissive resin layer includes two second polyimide resin films.

4. The display device according to claim 1 , wherein

at least one of the non-transmissive resin layer and the transmissive resin layer includes at least one inorganic insulating film, and

the at least one inorganic insulating film is removed in the connecting section in such a manner that the first polyimide resin film and the second polyimide resin film are connected directly to each other.

5. A method of manufacturing a display device including a non-transmissive display section and a transmissive display section, a bending portion being provided in a base member of the non-transmissive display section or a base member of the transmissive display section, the method comprising:

forming a non-transmissive resin layer in the base member of the non-transmissive display section by stacking a plurality of resin films including a first polyimide resin film;

forming a transmissive resin layer in the base member of the transmissive display section by stacking a plurality of resin films including a second polyimide resin film; and

forming a connecting section that connects the base member of the non-transmissive display section and the base member of the transmissive display section in such a manner that the connecting section and the bending portion do not overlap each other by stacking the plurality of resin films in the non-transmissive resin layer and the plurality of resin films in the transmissive resin layer,

wherein in forming the connecting section, at least one resin film in one of the non-transmissive resin layer and the transmissive resin layer is locked onto at least one resin film in another one of the non-transmissive resin layer and the transmissive resin layer, to form the connecting section with a convex-concave locking section,

wherein the convex-concave locking section anchors the at least one resin film in one of the non-transmissive resin layer and the transmissive resin layer to the at least one resin film in another one of the non-transmissive resin layer and the transmissive resin layer.

6. The method of manufacturing a display device according to claim 5 ,

wherein in forming the connecting section, an amount of a resin ejected from a nozzle of a slit coater to form the first polyimide resin film and the second polyimide resin film in the convex-concave locking section is adjusted to cause a thickness of the first polyimide resin film in the convex-concave locking section different from that in locations other than the convex-concave locking section and to cause a thickness of the second polyimide resin film in the convex-concave locking section different from that in locations other than the convex-concave locking section.

7. The method of manufacturing a display device according to claim 5 ,

wherein in forming the connecting section, the first polyimide resin film and the second polyimide resin film are subjected to laser fabrication, to cause a thickness of the first polyimide resin film in the convex-concave locking section different from that in locations other than the convex-concave locking section and to cause a thickness of the second polyimide resin film in the convex-concave locking section different from that in locations other than the convex-concave locking section.
