Flexible display with protector along side surface

1. A display comprising:

a display section including a flexible base and an image display layer that is supported by the flexible base and displays an image by utilizing an organic light-emitting phenomenon, the display section having a display surface on which the image is to be displayed, a back surface located opposite to the display surface, and a side surface located between the display surface and the back surface and coupled to each of the display surface and the back surface; and

a protector provided along at least a portion of the side surface of the display section, the protector including a metal layer and covering a region extending from a portion of the display surface through the side surface to a portion of the back surface,

wherein

both the display section and the protector are rollable in a predetermined rolling direction,

the protector includes a first protection part and a second protection part, the first protection part extending in the rolling direction and covering the portion of the display surface, the second protection part extending in the rolling direction and covering the portion of the back surface,

one of the first protection part and the second protection part has a protrusion that extends in the rolling direction and protrudes in a direction intersecting with the rolling direction, and

another of the first protection part and the second protection part has a groove that extends in the rolling direction and allows the protrusion to be fitted thereinto.

2. The display according to claim 1 , wherein the display section has an image display region in which the image is to be displayed, and the protector is provided in a region other than the image display region.

3. The display according to claim 1 , wherein the metal layer includes aluminum.

4. The display according to claim 1 , wherein the first protection part has the protrusion that extends in the rolling direction and protrudes in the direction intersecting with the rolling direction, and the second protection part has the groove that extends in the rolling direction and allows the protrusion to be fitted thereinto.

5. The display according to claim 1 , wherein the second protection part has the protrusion that extends in the rolling direction and protrudes in the direction intersecting with the rolling direction, and the first protection part has the groove that extends in the rolling direction and allows the protrusion to be fitted thereinto.

6. The display according to claim 1 , wherein a width of the protrusion varies.

7. The display according to claim 1 , wherein a width of the groove varies.

8. A display comprising:

a display section including a flexible base and an image display layer that is supported by the flexible base and displays an image by utilizing an organic light-emitting phenomenon, the display section having a display surface on which the image is to be displayed, a back surface located opposite to the display surface, and a side surface located between the display surface and the back surface and coupled to each of the display surface and the back surface; and

a protector provided along at least a portion of the side surface of the display section, the protector including a metal layer and covering a region extending from a portion of the display surface through the side surface to a portion of the back surface,

wherein

both the display section and the protector are rollable,

the metal layer includes biometal fiber, and

the display further comprises an energization controller that energizes the metal layer when the display section is in an unrolled state and that does not energize the metal layer when the display section is in a rolled state.

9. The display according to claim 8 , wherein the energization controller is operable to energize the metal layer such that the display is controlled to be flat.

10. The display according to claim 5 , wherein the metal layer exerts rigidity in an extending direction of the protector when under energization.

11. The display according to claim 8 , further comprising a physical switch for switching the energization controller between enabling and disabling energization.

12. The display according to claim 8 , wherein when the energization controller does not energize the metal layer, the display is in a soft state.
