Abstract: An electronic device, which comprises: at least two parts foldable in relation to each other, which can be turned into a first position and into a second position around a rotation axis; and a flexible display device, which extends over at least two foldable parts, covering them either entirely or partly. The flexible display device comprises: a folded position, to which the display device settles in the first position, and in which it folds around a first direction, which is parallel in relation to the rotation axis; and a curved position, to which the display device settles in the second position, and in which it curves around a second direction, which is transverse in relation to the rotation axis. A flexible display device can also be used with an electronic device.
