Abstract

A display device includes a display panel that has a curved part at least at a part of an outer edge of the display panel. The display device also includes a bent connector that is arranged along the curved part and electrically connected to the display panel.

First claim

What is claimed is:

1. A display device comprising:
a display panel that has a curved part at least at a part of an outer edge of the display panel; and
a bent connector arranged along the curved part and electrically connected to the display panel,
wherein the bent connector has insulating parts and conductive parts that are arranged alternately in an extending direction of the bent connector, the insulating parts being formed of an insulating member, and the conductive parts being formed of a conductive member, and
wherein the bent connector has an insulating layer on at least one of a convex side surface and a concave side surface of the bent connector at least at positions corresponding to the conductive parts.

2. The display device according to claim 1 ,
wherein the bent connector has a curved shape depending on curvature of the curved part.

3. The display device according to claim 1 ,
wherein the bent connector is bent by a larger amount per unit volume at the conductive parts than at the insulating parts.

4. The display device according to claim 2 ,
wherein the bent connector has an outer surface that is arranged facing a convex side of the curved part larger than an inner surface that is arranged facing in a concave side of the curved part.

5. The display device according to claim 2 ,
wherein the bent connector has a flexible part that is bent to a curved shape along the curved part.

6. The display device according to claim 5 ,
wherein the flexible part is a conductive part that is formed of a conductive member.

7. The display device according to claim 1 ,
wherein the bent connector has an uneven surface on a lateral surface, the uneven surface including recesses and projections that are alternately arranged in an extending direction of the bent connector.

8. The display device according to claim 7 ,
wherein the recesses are each formed of the insulating member and the projections are each formed of the conductive member.

9. The display device according to claim 1 ,
wherein the insulating layer has recess parts and projecting parts that are alternately arranged in an extending direction of the bent connector, and
wherein the bent connector has an uneven surface on a lateral surface including recesses and projections respectively formed by the recess parts and the projecting parts.

10. The display device according to claim 1 ,
wherein the insulating layer is arranged corresponding only to the conductive parts.

11. The display device according to claim 1 ,
wherein the display panel has electrodes that are connected to a first side of the bent connector, and
wherein the electrodes are arranged along the curved part.

12. The display device according to claim 11 , further comprising:
a substrate that is electrically connected to the display panel by the bent connector,
wherein the substrate has connection terminals that are connected to a second side of the bent connector that is not the first side, and
wherein the connection terminals are arranged along the curved part and corresponding to the electrodes of the display panel.

13. The display device according to claim 12 ,
wherein the substrate has a wiring area in which wires are arranged, the wiring area including a bundle area and an unbundle area,
wherein the wires are connected to the connection terminals,
wherein the wires are linear and bundled in the bundle area,
wherein the wires diverge from the bundle area toward the connection terminals in the unbundle area, and
wherein the unbundle area is along the curved part and corresponds to the connection terminals that are along the curved parts.

14. The display device according to claim 1 , further comprising:
a case having an arrangement part in which the bent connector along the curved part is arranged,
wherein the case has a chamfer at an edge of the arrangement part.

15. A timepiece comprising:
the display device according to claim 1 .
