Abstract

Provided is an electrophoretic display device that includes a display region including an electrophoretic element interposed between a first substrate and a second substrate that is flexible; and a conductive member that is located between the first substrate and the second substrate and at a position outside the display region and that electrically connects the substrates, the conductive member having a different thickness from that of the electrophoretic element; wherein the second substrate includes a slit formed at a position between the display region and the conductive member.

Claims (22)

1. An electrophoretic display device that includes a display region including an electrophoretic element interposed between a first substrate and a second substrate that is flexible, comprising:

a conductive member that is located between the first substrate and the second substrate and at a position outside the display region, and that electrically connects the substrates, the conductive member having a different thickness from that of the electrophoretic element;

wherein the second substrate includes a slit formed at a position between the display region and the conductive member.

2. The electrophoretic display device according to claim 1 ,

wherein the conductive member is thicker than the electrophoretic element.

3. The electrophoretic display device according to claim 1 ,

wherein the first substrate is also flexible.

4. The electrophoretic display device according to claim 1 ,

wherein the slit is formed with both ends thereof closed in the second substrate.

5. The electrophoretic display device according to claim 1 ,

wherein the slit includes a widened portion which is wider than the remaining portion of the slit, at least at an end portion of the slit.

6. The electrophoretic display device according to claim 1 ,

wherein the slit extends along a side of the conductive member facing the display region.

7. The electrophoretic display device according to claim 6 ,

wherein at least an end portion of the slit extends as far as a region outside the conductive member, in a longitudinal direction of the slit.

8. An electronic device comprising the electrophoretic display device according to claim 1 .

9. An electronic device comprising the electrophoretic display device according to claim 2 .

10. An electronic device comprising the electrophoretic display device according to claim 3 .

11. An electronic device comprising the electrophoretic display device according to claim 4 .

12. An electronic device comprising the electrophoretic display device according to claim 5 .

13. An electronic device comprising the electrophoretic display device according to claim 6 .

14. An electronic device comprising the electrophoretic display device according to claim 7 .
