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 non-linear part at least at a part of an outer edge of the display panel; a bent connector arranged along the non-linear part and electrically connected to the display panel; and a substrate that is electrically connected to the display panel by the bent connector, wherein the display panel has electrodes that are connected to a first side of the bent connector wherein the electrodes are arranged along the non-linear part, wherein the substrate has connection terminals that are connected to a second side of the bent connector that is not the first side, wherein the connection terminals are arranged non-linearly corresponding to the electrodes of the display panel, 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 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 non-linear part and corresponds to the connection terminals.

2 . The display device according to claim 1 ,
wherein the substrate has an antenna is arranged in an area that does not overlap the wiring area in a vertical direction to the substrate.

3 . The display device according to claim 1 ,
wherein a battery is arranged in an area that overlap the wiring area in a vertical direction to the substrate.

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

5 . The display device according to claim 4 ,
wherein the bent connector has insulating parts and conductive parts that are arranged alternately in an extending direction of the bent connector.

6 . The display device according to claim 5 ,
wherein the bent connector is bent by a larger amount per unit volume at the conductive parts than at the insulating parts.

7 . The display device according to claim 4 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.

8 . The display device according to claim 4 ,
wherein the bent connector has a flexible part that is bent to a curved shape along the curved part.

9 . The display device according to claim 8 ,
wherein the flexible part is a conductive part that is formed of a conductive member.

10 . 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.

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

12 . 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.

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