Abstract
A flexible display element capable of being rolled up and unfurled, comprises a back plate covering a back side of the display element, wherein the back plate comes into contact with the back side of the display element when the display element is rolled up, and at least a central portion of the back plate is separated from the display element to support the display element in a flat shape when the display element is unfurled. Thus, the display element and the back plate can be rolled up and carried with a simple configuration of the display element and the back plate, and the display element can be supported in a flat shape when unfurled. Therefore, it is possible to provide a flexible display element having high portability, ease of rolling, and retention of flatness during periods of use.
