6. The electronic device according to claim 5 , wherein a portion of the opening is in a folded region of the wiring substrate when the wiring substrate is bent to the side of the second surface.

7. The electronic device according to claim 3 , wherein a portion of the opening is in a folded region of the wiring substrate when the wiring substrate is bent to the side of the second surface.

8. The electronic device according to claim 5 , wherein
the substrate further includes a driving circuit outside of the display part,
the first input terminal group and the second input terminal group are connected to the driving circuit, and
the dummy input terminal group is in a floating state or grounded state.

9. The electronic device according to claim 1 , wherein the electronic component protrudes through the opening of the wiring substrate.

10. The electronic device according to claim 5 , wherein
the substrate is curved along the first direction,
the first surface is convex, and
the wiring substrate is bent to a curved region on the side of the second surface of the substrate.

11. The electronic device according to claim 1 , wherein
the input terminal part is arranged in a first direction,
