Abstract: The flexible display device includes a body, a flexible display, and a camera. The body includes a first body and a second body. The second body performs reciprocating movement relative to the first body between a first position and a second position. An area of the flexible display viewed from the front is larger when the second body is at the second position than when the second body is at the first position. When the second body is at the first position, the distance from a support to an edge of a third region is greater than the distance from the support to the camera. Accordingly, a range (stroke) of movement of the second body relative to the first body can be increased. In addition, when the second body is at the second position, the area of the flexible display viewed from the front can be increased.
