摘要： A flexible display device is disclosed. The flexible display device includes a first body, a second body, a flexible display, and a first cover. The second body performs reciprocating movement between a first position and a second position relative to the first body. The flexible display includes a first region, a first connected region, and a second connected region. When the second body is at the first position, the first cover covers the second connected region and forms a rear surface of the flexible display device. When switching between the first position and the second position is made, the user may hold the flexible display device in contact with the first region and the first cover.
