Abstract

A highly portable semiconductor device and the like providing improved browsability of display. Provided is a semiconductor device including a flexible display panel, a first housing supporting a first region of the display panel, a second housing supporting a second region of the display panel, and a flexible base material firmly attached to the first housing. The display panel can be deformed into an open position where the first and second regions are substantially on the same plane or into a folded position where the first and second regions overlap with each other. The second housing includes a groove portion where the flexible base material can partly slide. Part of the flexible base material is inserted into the groove portion in the open position. The part of the flexible base material which is inserted into the groove portion is at least partly withdrawn in a deformation into the folded position.

First claim

What is claimed is:

1. A display device comprising:
a flexible display panel;
a first housing that supports a first region of the flexible display panel;
a second housing that supports a second region of the flexible display panel; and
a first flexible base material that connects the first housing to the second housing,
wherein the display device is configured to be deformed between an opening position and a folded position,
wherein the flexible display panel is flat in the opening position,
wherein parts of the flexible display panel overlap with each other in the folded position,
wherein the first flexible base material is fixed to the first housing, and
wherein the second housing comprises a first groove portion into which the first flexible base material is inserted.

2. A display device comprising:
a flexible display panel;
a first housing that supports a first region of the flexible display panel;
a second housing that supports a second region of the flexible display panel; and
a first flexible base material that connects the first housing to the second housing,
wherein the display device is configured to be deformed between an opening position and a folded position,
wherein the flexible display panel is flat in the opening position,
wherein parts of the flexible display panel overlap with each other in the folded position,
wherein the first flexible base material is fixed to the first housing,
wherein the second housing comprises a first groove portion into which the first flexible base material is inserted, and
wherein the first flexible base material is slidable in the first groove portion during deformation of the display device.

3. The display device according to claim 2 , wherein the first flexible base material comprises an anchor portion in the first groove portion.

4. The display device according to claim 2 , comprising a second flexible base material that connects the first housing to the second housing,
wherein the flexible display panel is positioned between the first flexible base material and the second flexible base material.

5. The display device according to claim 4 ,
wherein the second housing comprises a second groove portion into which the second flexible base material is inserted, and
wherein the second flexible base material is slidable in the second groove portion during the deformation of the display device.

6. The display device according to claim 2 ,
wherein the flexible display panel comprises a light-emitting element.

7. The display device according to claim 2 ,
wherein the first flexible base material is attached to the first housing by an adhesive layer.

8. The display device according to claim 2 ,
wherein the flexible display panel is attached to the first housing by an adhesive layer.

9. The display device according to claim 2 ,
wherein the flexible display panel comprises a touch sensor.

10. The display device according to claim 2 ,
wherein the first housing comprises a first portion and a second portion attached to each other by a bonding layer, and
wherein the flexible display panel is positioned between the first portion and the second portion.

11. A display device comprising:
a flexible display panel;
a first housing that supports a first region of the flexible display panel;
a second housing that supports a second region of the flexible display panel;
a first flexible base material that connects the first housing to the second housing;
a first elastic body attaching the first flexible base material to the first housing; and
a second elastic body attaching the first flexible base material to the second housing,
wherein the display device is configured to be deformed between an opening position and a folded position,
wherein the flexible display panel is flat in the opening position, and
wherein parts of the flexible display panel overlap with each other in the folded position.

12. The display device according to claim 11 ,
wherein the flexible display panel is attached to the first housing by a third elastic body, and
wherein the flexible display panel is attached to the second housing by a fourth elastic body.

13. The display device according to claim 11 , comprising a second flexible base material that connects the first housing to the second housing,
wherein the flexible display panel is positioned between the first flexible base material and the second flexible base material.

14. The display device according to claim 13 ,
wherein the second housing comprises a second groove portion into which the second flexible base material is inserted, and
wherein the second flexible base material is slidable in the second groove portion during deformation of the display device.

15. The display device according to claim 11 ,
wherein the flexible display panel comprises a light-emitting element.

16. The display device according to claim 11 ,
wherein the first flexible base material is attached to the first housing by an adhesive layer.

17. The display device according to claim 11 ,
wherein the flexible display panel is attached to the first housing by an adhesive layer.

18. The display device according to claim 11 ,
wherein the flexible display panel comprises a touch sensor.

19. The display device according to claim 11 ,
